SN74CBT3244
SCDS001O – NOVEMBER 1992 – REVISED SEPTEMBER 2015
SN74CBT3244 Octal FET Bus Switch
1 Features
•1 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
3 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.
