PI74AVC+16245

2.5V 16-Bit Bidirectional Transceiver

with 3-State Outputs

Product Features

ProductDescription

• PI74AVC+16245 is designed for low-voltage operation,

V_CC= 1.65V to 3.6V

ThePI74AVC+16245isa16-bitbidirectionaltransceiverdesigned

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

OutputEnablecontrolsaredesignedtooperate thisdeviceaseither

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.

• True ±24mA Balanced Drive @ 3.3V

• Compatible with Philips and T.I.AVC Logic family

• I_OFFsupports partial power-down operation

• 3.6V I/O Tolerant inputs and outputs

• All outputs contain a patented DDC

(Dynamic Drive Control) circuit that reduces noise

without degrading propagation delay

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

down, OE should be tied to V through a pull-up resistor; the

minimum value of the resistor is determined by the current sinking

ability of the driver.

• Industrial operation: –40°C to +85°C

• Packaging (Pb-free & Green available):

– 48-pin 240-mil wide plastic TSSOP

– 48-pin 173-mil wide plastic TVSOP
