PI74FCT162500T

Fast CMOS 18-Bit

Registered Transceivers

Product Description:

Pericom Semiconductors PI74FCT series of logic circuits are pro-

duced in the Companys advanced 0.8 micron CMOS technology,

achieving industry leading speed grades.

CommonFeatures:5

PI74FCT16500TandPI74FCT162500Tarehigh-speed,

low power devices with high current drive.

ThePI74FCT16500TandPI74FCT162500Tare18-bit registeredbus

transceivers designed with D-type latches and flip-flops to allow

data flow in transparent, latched, and clocked modes. The Output

Enable (OEAB and OEBA), Latch Enable (LEAB and LEBA) and

Clock (CLKAB and CLKBA) inputs control the data flow in each

direction. When LEAB is HIGH, the device operates in transparent

modeforA-to-Bdataflow. WhenLEABisLOW,theAdataislatched

if CLKAB is held at a HIGH or LOW logic level. The A bus data is

stored in the latch/flip-flop on the HIGH-to-LOW transition of

CLKAB, if LEAB is LOW. OEAB performs the output enable

functionontheBport. DataflowfromBporttoAportissimilarusing

OEBA, LEBA and CLKBA. These high-speed, low power devices

offer a flow-through organization for ease of board layout.

PI74FCT16500TFeatures:

High output drive: I^OH= 32 mA; IOL = 64 mA

Power off disable outputs permit live insertion

Typical VOLP (Output Ground Bounce) < 1.0V

atVCC =5V,TA =25°C

The PI74FCT16500T output buffers are designed with a Power-Off

disable allowing live insertion of boards when used as backplane

drivers.

PI74FCT162500TFeatures:

Balanced output drivers: ±24 mA

Reduced system switching noise

The PI74FCT162500T has ±24 mA balanced output drivers. It is

designed with current limiting resistors at its outputs to control the

output edge rate resulting in lower ground bounce and undershoot.

This eliminates the need for external terminating resistors for most

interface applications.

Typical VOLP (Output Ground Bounce) < 0.6V
