HD74ALVCH162270

12-bit to 24-bit Registered Bus Exchanger with 3-state Outputs

ADE-205-178A (Z)

2nd. Edition

March 1998

Description

The HD74ALVCH162270 is used in applications where data must be transferred from a narrow high speed

bus to a wide lower frequency bus. The device provides synchronous data exchange between the two ports.

Data is stored in the internal registers on the low to high transition of the clock (CLK) input when the

appropriate CLKEN inputs are low. The select (SEL) line selects 1B or 2B data for the A outputs. For data

transfer in the A to B direction, a two stage pipeline is provided in the A to 1B path, with a single storage

be presented synchronously as a 24-bit word on the B port. Data flow is controlled by the active low output

enables (OEA, OEB). The control terminals are registered to synchronize the bus direction changes with

CLK. 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.
