HD74ALVCH162374

16-bit Edge triggered D-type Flip Flops with 3-state Outputs

ADE-205-180B (Z)

Preliminary

3rd. Edition

October 1997

Description

The HD74ALVCH162374 is particularly suitable for implementing buffer registers, I/O ports, bidirectional

bus drivers, and working registers. It can be used as two 8-bit flip flops or one 16-bit flip flop. On the

positive transition of the clock (CLK) input, the Q outputs of the flip flop take on the logic levels set up at

the data (D) inputs.

The output enable (OE) input can be used to place the eight outputs in either a normal logic state (high or

low logic levels) or a high impedance state. In the high impedance state, the outputs neither load nor drive

the bus lines significantly. The high impedance state and the increased drive provide the capability to drive

bus lines without need for interface or pullup components. OE does not affect internal operations of the

flip flops. Old data can be retained or new data can be entered while the outputs are in the high impedance

state.

Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level. All

outputs, which are designed to sink up to 12 mA, include 26 Ω resistors to reduce overshoot and

undershoot.

Features

•

V_CC= 2.3 V to 3.6 V

Typical V_OLground bounce < 0.8 V (@V_CC= 3.3 V, Ta = 25°C)

Typical V_OHundershoot > 2.0 V (@V_CC= 3.3 V, Ta = 25°C)

High output current ±12 mA (@V_CC= 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.
