HD74ALVC162334

16-bit Universal Bus Driver with 3-state Outputs

ADE-205-205A (Z)

2nd. Edition

December 1999

Description

This HD74ALVC162334 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 (OE) 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.

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

and undreshoot.

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)

All outputs have equivalent 26 Ω series resistors, so no external resistors are required

Notes:

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage

to the device. These are stress ratings only, and functional operation of the device at these or

any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute maximum rated conditions for extended periods may affect device

reliability.

1. The input and output negative voltage ratings may be exceeded if the input and output clamp

current ratings are observed.

2. This value is limited to 4.6 V maximum.

3. The maximum package power dissipation is calculated using a junction temperature of 150°C

and a board trace length of 750 mils.

Notes:

1. All input pulses are supplied by generators having the following characteristics :

PRR ≤ 10 MHz, Zo = 50 Ω, t_r≤ 2.0 ns, t_f≤ 2.0 ns. (V_CC= 2.5±0.2 V)

PRR ≤ 10 MHz, Zo = 50 Ω, t_r≤ 2.5 ns, t_f≤ 2.5 ns. (V_CC= 2.7 V, 3.3±0.3 V)

2. Waveform – A is for an output with internal conditions such that the output is low except

when disabled by the output control.

3. Waveform – B is for an output with internal conditions such that the output is high except

when disabled by the output control.

4. The output are measured one at a time with one transition per measurement.
