U74HCT640 - OCTAL BUS TRANSCEIVERS

Datasheet Summary

Description

The U74HCT640 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 B bus to the A bus.

Features

  • S.
  • Inputs are TTL-voltage compatible.
  • Typical tPD of 12ns at 5.5V, CL=50pF.
  • Low power consumption, ICC = 8μA (Max) at 5.5V.
  • ±6mA output driver at 4.5V CMOS IC DIP-20 SOP-20 SSOP-20 TSSOP-20.

UNISONIC TECHNOLOGIES CO., LTD U74HCT640 OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS  DESCRIPTION The U74HCT640 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 B bus to the A bus. When OE is high, the buses are effectively isolated. When OE is low, the buses are enable.  FEATURES * Inputs are TTL-voltage compatible * Typical tPD of 12ns at 5.5V, CL=50pF * Low power consumption, ICC = 8μA (Max) at 5.5V * ±6mA output driver at 4.
