PI74ALVCH16501

18-Bit Universal Bus Transceiver

With 3-State Outputs

Product Features

ProductDescription

Pericom Semiconductor’s PI74ALVCH series of logic circuits are

producedintheCompany’sadvanced0.5micronCMOStechnology,

achieving industry leading speed.

• PI74ALVCH16501 is designed for low voltage operation

• V = 2.3V to 3.6V

• Hysteresis on all inputs

< 0.8V at V = 3.3V, T = 25°C

Data flow in each direction is controlled by Output Enable (OEAB

and OEBA), Latched Enable (LEAB and LEBA), and CLOCK

(CLKAB and CLKBA) inputs. For A-to-B data flow, the device

< 2.0V at V = 3.3V, T = 25°C

• 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:

– 48-pin 240 mil wide plastic TSSOP (A)

– 48-pin 300 mil wide plastic SSOP (V)

down, OEBA should be tied to V through a pull-up resistor and

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

Active bus-hold circuitry is provided to hold unused or floating

data inputs at a valid logic level.
