HD74ALVCH162244 Datasheet 16-bit Buffers / Drivers With 3-state Outputs

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74ALVCH162244 16-bit Buffers / Drivers with 3-state Outputs ADE-205-173A (Z) Preliminary 2nd.

General Description

The HD74ALVCH162244 is designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus oriented receivers and transmitters.

The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer.

It provides true outputs and symmetrical active-low output-enable ( OE) inputs.

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 ±12 mA (@VCC = 3.0 V).
  • Bus hold on data inputs eliminates the need for external pullup / pulldown resistors.
  • All outputs have equivalent 26 Ω series resistors, so no external resistors are required. HD74ALVCH162244 Function Table Inputs OE L L H H : High level L : Low level X : Imma.
