PI74ALVCH16543

16-Bit Registered Transceiver

with 3-State Outputs

Logic Block Diagram

Product Description

Pericom Semiconductors PI74ALVCH series of logic circuits are
produced in the Companys advanced 0.5 micron CMOS technology,
achieving industry leading speed.

The PI74ALVCH16543, a 16-bit registered transceiver designed
for 2.3V to 3.6V VCC operation, can be used as two 8-bit transceivers
or one 16-bit transceiver. Separate Latch Enable (LEAB or LEBA),
and Output Enable (OEAB and OEBA) inputs are provided for each
register to permit independent control in either direction of data
flow.

The A-to-B Enable (CEAB) input must be LOW to enter data from
A or to output data from B. If CEAB is LOW and LEAB is LOW,
the A-to-B latches are transparent; a subsequent low-to-high
transition of LEAB puts the A latches in the storage mode. With
CEAB and OEAB both LOW, the 3-State B outputs are active and
reflect the data present at the output of the A latches. Data flow from
B to A is similar but requires using CEBA, LEBA, and OEBA.

To ensure the high-impedance state during power up or power
down, OE should be tied to VCC through a pull-up 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.

Product Features

• PI74ALVCH16543 is designed for low voltage operation

• V

CC

= 2.3V to 3.6V

• Hysteresis on all inputs

• Typical V

OLP

(Output Ground Bounce)

< 0.8V at VCC = 3.3V, TA = 25°C

• Typical V

OHV

(Output VOH Undershoot)

< 2.0V at VCC = 3.3V, TA = 25°C

• Bus Hold retains last active bus state during 3-State,

Notes:

1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.

2. Typical values are at VCC = 3.3V, +25°C ambient and maximum loading.

3. Unused Control Inputs must be held HIGH or LOW to prevent them from floating.
