TC74LCX652FS

Low-Voltage Octal Bus Transceiver/Register with 5-V Tolerant Inputs and Outputs

The TC74LCX652FS is a high-performance CMOS octal bus

transceiver/register. Designed for use in 3.3-V systems, it

achieves high-speed operation while maintaining the CMOS low

power dissipation.

but it could be used to interface to 5-V supply environment for

both inputs and outputs.

This device is bus transceiver with 3-state outputs, D-type

flip-flops, and control circuitry arranged for multiplexed

transmission of data directly from the internal registers.

All inputs are equipped with protection circuits against static

discharge.

Features

• Latch-up performance: −500 mA

• Available in SSOP

• Bidirectional interface between 5 V and 3.3 V signals

• Power-down protection provided on all inputs and outputs

• Pin and function compatible with the 74 series (74AC/F/ALS/LS etc.) 652 type

Note 1: Do not apply a signal to any bus pins when it is in the output mode. Damage may result.

All floating (high impedance) bus pins must have their input levels fixed by means of pull-up or pull-down

resistors.

Weight: 0.14 g (typ.)
