Product Features
ProductDescription
Pericom Semiconductors PI74ALVCH series of logic circuits are
producedintheCompanysadvanced0.5micronCMOStechnology,
achieving industry leading speed.
• PI74ALVCH16543 is designed for low voltage operation
• V = 2.3V to 3.6V

• Bus Hold retains last active bus state during 3-State,
eliminating the need for external pullup resistors
• Industrial operation at 40°C to +85°C
• Packages available:
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
reflectthedatapresentattheoutputoftheAlatches. Dataflowfrom
B to A is similar but requires using CEBA, LEBA, and OEBA.
56-pin 240 mil wide plastic TSSOP (A)
56-pin 300 mil wide plastic SSOP (V)
To ensure the high-impedance state during power up or power
down, OE should be tied to V through a pull-up resistor; the
CC
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.

(Above which the useful life may be impaired. For user guidelines, not tested.)
Note:
Storage Temperature ...................................................................... 65°C to +150°C
Ambient Temperature with Power Applied ................................... 40°C to +85°C
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the device.
This is a stress rating only and functional operation of the
device at these or any other conditions above those
indicated in the operational sections of this specification
is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
