Registered Transceivers

Product Features

Product Description

CommonFeatures:

Pericom Semiconductors PI74FCT series of logic circuits are

producedintheCompanysadvanced 0.6micronCMOStechnology,

achieving industry leading speed grades.

PI74FCT16646T,PI74FCT162646T,andPI74FCT162H646are

high-speed, low power devices with high current drive

The PI74FCT16646T, PI74FCT162646T, and PI74FCT162H646

are 16-bit registered transceivers organized as two independent

8-bit bus transceivers designed with 3-state D-type flip-flops and

control circuitry arranged for multiplexed transmission of data

directlyfromthedatabusorfromtheinternalstorageregisters.Each

8-bittransceiverutilizestheenablecontrol(xOE)anddirectionpins

(xDIR) to control the transceiver functions. The Select (xSAB and

xSBA) control pins are used to select either real-time or stored data

transfer. The circuitry used for select control will eliminate the

typical decoding glitch that occurs in a multiplexer during the

transition between real-time and stored data. A low input level

selects real-time data and a high selects stored data.

PI74FCT16646TFeatures:

High output drive: I = 32mA; I = 64mA

Power off disable outputs permit live insertion

Typical V (Output Ground Bounce)

OLP

< 1.0V at V = 5V, T = 25°C

ThePI74FCT16646ToutputbuffersaredesignedwithaPower-Off

disable allowing live insertion of boards when used as backplane

drivers.

The PI74FCT162646T has ±24mA 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.

PI74FCT162646T Features:

Balanced output drivers: ±24mA

Reduced system switching noise

Typical V

(Output Ground Bounce)

OLP

< 0.6V at V = 5V, T = 25°C

PI74FCT162H646T Features:

Bus Hold retains last active bus state during Three-state

Eliminates the need for external pull-up resistors

The PI74FCT162H646T has Bus Hold which retains the inputs

last state whenever the input goes to high-impedance preventing
