SN74ALVCH16821 - 3.3-V 20-BIT BUS-INTERFACE FLIP-FLOP

General Description

This 20-bit bus-interface flip-flop is designed for 1.65-V to 3.6-V VCC operation.

The SN74ALVCH16821 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.

Key Features

  • Member of the Texas Instruments Widebus™ Family.
  • Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors.
  • Latch-Up Performance Exceeds 250 mA Per JESD 17.
  • ESD Protection Exceeds JESD 22.
  • 2000-V Human-Body Model (A114-A).
  • 200-V Machine Model (A115-A).

The SN74ALVCH16821 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.
