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

– 48-pin plastic 240-mil TSSOP (A)

– 48-pin plastic 173-mil TVSOP (K)

PI74AVC164245LA

Description

Pericom Semiconductor’s PI74AVC164245LA, a 16-bit (dual-octal)

noninverting bus transceiver, contains two separate supply rails:

B port (VCCB), set at 3.3V, and A port (VCCA), set to operate

at 1.5-2.5V. This arrangement permits translation from a 1.5-2.5V to

3.3V environment and vice versa. The control pins, OE and DIR are

controlled by VCCB .

The PI74AVC164245LA is designed for asynchronous

communication between data buses.

To ensure the high impedance state during power up or power

down, the output-enable (OE) input should be tied to VCC through

a pullup resistor: the minimum value of the resistor is determined by

the current-sinking capability of the driver.

Note:

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.

Maximum Ratings

(Absolute maximum ratings over operating free-air temperature range from VCCB at 3.3V & VCCA at 1.5 - 2.5V, unless otherwise noted)

Notes:

1. This value is limited to 4.6V maximum.

2. This value is limited to 3.8V maximum.

3. The package thermal impedance is calculated in accordance with JESD 51.

4. To ensure proper device operation, all unused device inputs must be held at the associated VCC or GND.

Notes:

1. Value limited to 4.6V maximum..

2.To ensure proper device operation, all unused device inputs must be held at the associated VCC or GND.

3. Typical values are measured at VCC = 3.3V, TA = 25°C
