SN74CBT3244 (ACTIVE) Octal FET Bus Switch

Octal FET Bus Switch - SN74CBT3244
Datasheet
 

Description

The SN74CBT3244 device provides eight bits of high-speed TTL-compatible bus switching. The SOIC, SSOP, TSSOP, and TVSOP packages provide a standard ’244 device pinout. The low ON-state resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as two 4-bit low-impedance switches with separate output-enable (OE) inputs.

Features

  • High-Bandwidth Data Path (Up to 200 MHz)
  • Control Inputs Can Be Driven by TTL or 5-V/3.3-V
    CMOS Outputs
  • Low and Flat ON-State Resistance (ron)
    Characteristics Over Operating Range
    (ron= 5 Ω Typical)
  • Bidirectional Data Flow With Near-Zero
    Propagation Delay
  • Low Input/Output Capacitance Minimizes Loading
    and Signal Distortion
    (Cio(OFF) = 6 pF Typical)
  • Low Power Consumption (ICC = 50 µA Maximum)
  • VCC Operating Range From 4.5 V to 5 V
  • Data I/Os Support 0- to 5-V Signaling Levels (0.8
    V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, 5 V)
  • Standard ’244-Type Pinout
