U74LVC640 Datasheet PDF - Unisonic Technologies OCTAL BUS TRANSCEIVER Specs

U74LVC640 - OCTAL BUS TRANSCEIVER

Datasheet Summary

Description

The U74LVC640 is designed for asynchronous communication between data buses and has inverting outputs.

While the direction-control(DIR) input is high, data transmits from the A bus to the B bus.

In contrast, Data transmits from the B bus to the A bus DIR input is low.

Features

ES.
Supply Voltage Range From 1.2V to 3.6V.
Input Accept Voltages up to 5.5V.
Partial-Power-Down Mode Operation.
Max tPD is 6.3ns at 3.3V.

UNISONIC TECHNOLOGIES CO., LTD U74LVC640 OCTAL BUS TRANSCEIVER WITH 3-STATE INVERTING OUTPUTS DESCRIPTION CMOS IC The U74LVC640 is designed for asynchronous communication between data buses and has inverting outputs. While the direction-control(DIR) input is high, data transmits from the A bus to the B bus. In contrast, Data transmits from the B bus to the A bus DIR input is low. The output-enable(OE) will disable the device and isolate from the buses when high voltage is applied on it.
