HD74ALVCH16821 Datasheet 3.3-v 20-bit Bus Interface Flip Flops With 3-state Outputs

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74ALVCH16821 3.3-V 20-bit Bus Interface Flip Flops with 3-state Outputs ADE-205-171B (Z) 3rd.

General Description

The HD74ALVCH16821 can be used as two 10-bit flip flops or one 20-bit flip flop.

The 20 flip flops are edge triggered D-type flip flops.

On the positive transition of the clock (CLK) input, the device provides true data at the Q outputs.

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 HD74ALVCH16821 Function Table Inputs OE L L L H CLK ↑ ↑ H or L X D H L X X H L Q0.
  • 1 Z Output Q H : High level L : Low level X : Immaterial Z : High impedance ↑ : Low to high tra.
