Block Diagram
Pin Configuration (28-Pin TQFN)
Description
Pericom Semiconductor’s PI74AVC164245, a 16-bit (dual-octal)
noninverting bus transceiver, contains two separate supply rails:
B port (V
CCB), set at 3.3V, and A port (VCCA), set to operate
at 1.2-2.5V. This arrangement permits translation from a 1.2-2.5V
to 3.3V environment and vice versa.
ThePI74AVC164245isdesignedforasynchronouscommunication
between data buses.
To ensure the high impedance state during power up or power
down, the output-enable (OE) input should be tied to V
CCB through
a pullup resistor: the minimum value of the resistor is determined
by the current-sinking capability of the driver.
Features
PI74AVC164245 is designed for low voltage operation:
1.2V - 2.5V to 3.3V
Industrial operation at –40°C to +85°C
Packaging (Pb-free & Green):
– 48-pin plastic 300-mil SSOP (V)
– 48-pin plastic 240-mil TSSOP (A)
– 48-pin plastic 173-mil TVSOP (K)
