HD74ALVCH16245

16-bit Bus Transceivers with 3-state Outputs

ADE-205-134C (Z)

4th. Edition

December 1999

Description

The HD74ALVCH16245 is designed for asynchronous communication between data buses. The control

function implementation minimizes external timing requirements. This device can be used as two 8-bit

transceivers or one 16-bit transceiver. It allow data transmission from the A bus to the B bus or from the B

bus to the A bus depending upon the logic level at the direction control (DIR) input. The output enable

(OE) input can be used to disable the device so that the buses are effectively isolated. Active bus hold

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

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)

Bus hold on data inputs eliminates the need for external pullup / pulldown resistors

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 condition” 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, tr ≤ 2.5 ns, tf ≤ 2.5 ns.

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.
