TC7MB3244FT, TC7MB3244FK

Octal Bus Switch

The TC7MB3244 provides eight bits of high-speed

TTL-compatible bus switching in a standard ’244 device pinout.

The low on resistance of the switch allows connections to be made

with minimal propagation delay.

The device is organized as two 4-bit low-impedance switches

switch is on and data can flow from port A to port B, or vice versa.

exists between the two ports.

All inputs are equipped with protection circuits against static

discharge.

Features

• ESD performance: Machine model ≥ ±200 V

Human body model

≥ ±2000 V

• Compatible with TTL outputs (control inputs)

• Package: TSSOP20,VSSOP20 (US20)

• Pin compatible with the 74xx244 type.

Functionally equivalent to (FST/CBT) 3244.
