HD74ALVCH16721 Datasheet 3.3-v 20-bit Flip Flops With 3-state Outputs

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74ALVCH16721 3.3-V 20-bit Flip Flops with 3-state Outputs ADE-205-139B (Z) 3rd.

General Description

The HD74ALVCH16721’s twenty flip flops are edge triggered D-type flip flops with qualified clock storage.

On the positive transition of the clock (CLK) input, the device provides true data at the Q outputs, provided that the clock enable (CLKEN ) input is low.

If CLKEN is high, no data is stored.

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 HD74ALVCH16721 Function Table Inputs OE L L L L H CLKEN H L L L X CLK X ↑ ↑ L or H X D X H L X X Q0.
