Product Description
Pericom Semiconductors PI74ALVCH series of logic circuits are
produced using the Companys advanced 0.5 micron CMOS
technology, achieving industry leading speed grades.
The PI74ALVCH16245 is a 16-bit bidirectional transceiver
designed for asynchronous two-way communication between
data buses. The direction control input pin (xDIR) determines
the direction of data flow through the bidirectional transceiver. The
Direction and Output Enable controls are designed to operate
this device as either two independent 8-bit transceivers or one
16-bit transceiver. The output enable (OE) input, when HIGH,
disables both A and B ports by placing them in HIGH Z condition.
To ensure the high-impedance state during power up or power
down, OE should be tied to V
CC
through a pull-up resistor; the
minimum value of the resistor is determined by the current sinking
ability of the driver.
Active bus-hold circuitry is provided to hold unused or floating
data inputs at a valid logic level.
Product Features
PI74ALVCH16245 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 V
CC
= 3.3V, T
