PI74ALVCHR162524

18-Bit Registered Bus Transceiver

with 3-State Outputs

ProductDescription

Product Features

Pericom Semiconductors PI74ALVCH series of logic circuits are

produced using the Companys advanced 0.5 micron CMOS

technology, achieving industry leading speed.

• PI74ALVCHR162524 is designed for low voltage operation

• V = 2.3V to 3.6V

• A & B parts have equivalent 26 Ohm series resistors

ThePI74ALVCHR162524data flowineachdirectioniscontrolledby

output-enable (OEAB and OEBA) and clock-enable (CLKENBA)

inputs. For the A-to-B data flow, the data flows through a single

buffer. The B-to-A data can flow through a four-stage pipeline

state of the select (SEL) input.

• Typical V

(Output Ground Bounce)

OLP

< 0.8V at V = 3.3V, T = 25°C

• Typical V

(Output V Undershoot)

OHV

< 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:

Data is stored in the internal registers on the low-to-high

transition of the clock (CLK) input, provided that the appropriate

CLKENBA input is low. The B-to-A data transfer is synchronized

with CLK.

56-pin 240 mil wide plastic TSSOP (A)

56-pin 300 mil wide plastic SSOP (V)

To reduce overshoot and undershoot, the A and B-port outputs

include 26-ohm series resistors.

Toensurethehigh-impedancestateduringpoweruporpowerdown,

OE should be tied to Vcc through a pull-up resistor; the minimum

value of the resistor is determined by the current-sinking capability

of the driver.

The PI74ALVCHR162524 has Bus Hold which retains the data

inputs last state whenever the data input goes to high-impedance

preventing floating inputs and eliminating the need for pullup/

down resistors.
