HD74ALVCH162334

16-bit Universal Bus Driver with 3-state Outputs

ADE-205-210 (Z)

Preliminary

1st. Edition

December 1997

Description

This HD74ALVCH162334 is a 16-bit universal bus driver is designed for 2.3 V to 3.6 V V_CCoperation.

Data flow from A to Y is controlled by the output enable (O E) input. The device operates in the

transparent mode when the latch enable (LE) input is low. When LE is high, the A data is latched if the

clock (CLK) input is held at a high or low logic level. If LE is high, the A data is stored in the latch/flip

flop on the low to high transition of CLK. When OE is high, the outputs are in the high impedance state.

To ensure the high impedance state during power up or power down, OE should be tied to V_CCthrough a

pullup resistor; the minimum value of the resistor is determined by the current sinking capability of the

driver.

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
