U74HC640 - OCTAL BUS TRANSCEIVERS

Datasheet Summary

Description

The U74HC640 is a octal bus transceivers with 3-state outputs.

It is designed for asynchronous two-way communication between data buses.

Depending on the direction-control (DIR) input, data are transmitted from the A bus to the B bus or from the B bus to the A bus.

Features

  • S.
  • Wide Supply Voltage Range from 2V to 6V.
  • Typical tPD of 8ns at 6V, CL=50pF.
  • Low Power Consumption, ICC = 8μA (Max) at 5.5V.
  • ±7.8mA Output Driver at 6V.

UNISONIC TECHNOLOGIES CO., LTD U74HC640 OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS  DESCRIPTION The U74HC640 is a octal bus transceivers with 3-state outputs. It is designed for asynchronous two-way communication between data buses. Depending on the direction-control (DIR) input, data are transmitted from the A bus to the B bus or from the B bus to the A bus. When OE is high, the buses are effectively isolated. When OE is low, the buses are enable.  FEATURES * Wide Supply Voltage Range from 2V to 6V * Typical tPD of 8ns at 6V, CL=50pF * Low Power Consumption, ICC = 8μA (Max) at 5.5V * ±7.8mA Output Driver at 6V  ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74HC640L-R20-R U74HC640G-R20-R Package SSOP-20 CMOS IC Packing Tape Reel  MARKING www.unisonic.com.
