6 Specifications

6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
VCC Supply voltage –0.5 7 V
VI Input voltage(2) –0.5 7 V
Continuous channel current 128 mA
IIK Input clamp current, (VI < 0) 50 mA
Tstg Storage temperature –65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.

6.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±1000 V
Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±1500
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

6.3 Recommended Operating Conditions

over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
VCC Supply voltage 4 5.5 V
VIH High-level control input voltage 2 V
VIL Low-level control input voltage 0.8 V
TA Operating free-air temperature –40 85 °C
(1) All unused control inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, SCBA004.

6.4 Thermal Information

THERMAL METRIC(1) SN74CBT16214 UNIT
DGG (TSSOP) DL (SSOP)
56 PINS 56 PINS
RθJA Junction-to-ambient thermal resistance 64 56 °C/W
(1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report, SPRA953.

6.5 Electrical Characteristics

over recommended operating free-air temperature range (unless otherwise noted)
PARAMETER TEST CONDITIONS MIN TYP(1) MAX UNIT
VIK VCC = 4.5 V, II = –18 mA –1.2 V
II VCC = 0, VI = 5.5 V 10 µA
VCC = 5.5 V, VI = 5.5 V or GND ±1
ICC VCC = 5.5 V, IO = 0, VI = VCC or GND 3 µA
∆ICC(2) Control inputs VCC = 5.5 V, One input at 3.4 V, Other inputs at VCC or GND 2.5 mA
Ci VI = 3 V or 0 4 pF
Cio(OFF) VO = 3 V or 0, S0, S1, and S2 = GND 7.5 pF
ron(3) VCC = 4 V,
TYP at VCC = 4 V		 VI = 2.4 V, II = 15 mA 14 20 Ω
VCC = 4.5 V VI = 0 II = 64 mA 4 7 Ω
II = 30 mA 4 7
VI = 2.4 V, II = 15 mA 6 12
(1) All typical values are at VCC = 5 V (unless otherwise noted), TA = 25°C.
(2) This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
(3) Measured by the voltage drop between the A and B terminals at the indicated current through the switch. ON-state resistance is determined by the lower of the voltages of the two (A or B) terminals.

6.6 Switching Characteristics

over recommended operating free-air temperature range, CL = 50 pF (unless otherwise noted) (see Figure 2)
PARAMETER FROM
(INPUT)		 TO
(OUTPUT)		 VCC = 4 V VCC = 5 V ± 0.5 V UNIT
MIN MAX MIN MAX
tpd(1) A or B B or A 0.35 0.25 ns
tpd S B or A 15.3 5.5 13.9 ns
ten S A or B 16 5.1 14.5 ns
tdis S A or B 12.1 3.6 11.7 ns
(1) The propagation delay is the calculated RC time constant of the typical ON-state resistance of the switch and the specified load capacitance, when driven by an ideal voltage source (zero output impedance).
