5.6 Switching Characteristics

at TA = 25°C and VDD = 5V (unless otherwise noted); characteristic values are specified by design, characterization, or both
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
Temperature sensitivity of timing internal TA = –40°C to +125°C, CT = 0.1μF, 
RA = RB = 1kΩ to 100kΩ (2)		 75 ppm/°C
Supply voltage sensitivity of timing interval V+ = 3.3V to 15V, CT = 0.1μF, RA = RB = 1kΩ to 100kΩ 0.17 %/V
tr Output pulse rise time RL = 10MΩ, CL = 10pF 7.8 ns
tf Output pulse fall time RL = 10MΩ, CL = 10pF 4.7 ns
fmax Maximum frequency, astable mode (1) RA = 470Ω, RB = 200Ω,
CT = 200pF		 2.6 3 MHz
VDD = 15V 3.1
Free-running oscillator, THRES = TRIG = OUT 7.2
tPD Trigger propagation delay Rising VDD = 3.3V 85 ns
VDD = 5V 75
VDD = 15V 60
Falling VDD = 3.3V 70
VDD = 5V 50
VDD = 15V 50
(1) This measurement is significantly impacted by board parasitics.
(2) Calculated as (f125°C – f–40°C) / (ΔTA × f25°C) × 106 where fT = output frequency at temperature T, and TA = –40°C to +125°C.
