HD74ALVCH16543 Datasheet 16-bit Registered Transceivers With 3-state Outputs

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74ALVCH16543 16-bit Registered Transceivers with 3-state Outputs ADE-205-169A (Z) 2nd.

General Description

The HD74ALVCH16543 can be used as two 8-bit transceivers or one 16-bit transceiver.

Separate latch enable (LEAB or LEBA ) and output enable (OEAB or OEBA ) inputs are provided for each register to permit independent control in either direction of data flow.

The A to B enable (CEAB) input must be low in order to enter data from A or to output data from B.

Key Features

  • VCC = 2.3 V to 3.6 V.
  • Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C).
  • Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C).
  • High output current ±24 mA (@V CC = 3.0 V).
  • Bus hold on data inputs eliminates the need for external pullup / pulldown resistors HD74ALVCH16543 Function Table.
