PI74ALVCH32501

36-Bit Universal Bus Transceiver

with 3-State Outputs

Product Features

ProductDescription

Pericom Semiconductors PI74ALVCH series of logic circuits are

produced using the Companys advanced 0.5 micron CMOS

technology, achieving industry leading speed.

· PI74ALVCH32501 is designed for low voltage operation,

Vcc = 1.65 to 3.6V

· Bus Hold on data inputs eliminates the need for external

pullup resistors

The36-bitPI74ALVCH32501universalbustransceiver isdesigned

for1.65Vto3.6VV operation.

· Industrial operation at 40ºC to 85ºC

· Packages available:

This device can be used as two 18-bit transceivers or one 36-bit

transceiver. Data flow in each direction is controlled by output-

enable (OEAB and OEBA), latch-enable (LEAB and LEBA), and

clock(CLKABandCLKBA)inputs.ForA-to-Bdataflow,thedevice

operatesinthetransparentmodewhen LEABishigh. WhenLEAB

is low, the A-data is latched if CLKAB is held at a

high or low logic level. If LEAB is low, the A data is stored in the

latch/flip-flop on the low-to-high transition of CLKAB.

WhenOEABishigh,theoutputsareactive.WhenOEABislow,the

outputs are in the high-impedance state.

DataflowforBtoAissimilar tothatofAtoBbutusesOEBA,LEBA,

and CLKBA. The output enables are complementary (OEAB is

active high and OEBA is active low).

To ensure the high-impedance state during power up or power

down, OEBA should be tied to V through a pullup resistor and

OEAB should be tied to GND through a pulldown resistor; the

minimumvalue 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 logic level.

The PI74ALVCH32501 is characterized for operation from

40°C to 85°C.
