IDT54/74FCT652T/AT/CT/DT - 2652T/AT/CT

FAST CMOS OCTAL

TRANSCEIVER/

REGISTERS (3-STATE)

Integrated Device Technology, Inc.

FEATURES:

• Common features:

– Low input and output leakage ≤1µA (max.)

– Extended commercial range of –40°C to +85°C

– CMOS power levels

– True TTL input and output compatibility

– VOH = 3.3V (typ.)

DESCRIPTION:

TheFCT646T/FCT2646T/FCT648T/FCT652T/2652Tcon-

sist of a bus transceiver with 3-state D-type flip-flops and

control circuitry arranged for multiplexed transmission of data

directly from the data bus or from the internal storage regis-

ters.

The FCT652T/FCT2652T utilize GAB and GBA signals to

control the transceiver functions. The FCT646T/FCT2646T/

FCT648T utilize the enable control (G) and direction (DIR)

pins to control the transceiver functions.

SABandSBAcontrolpinsareprovidedtoselecteitherreal-

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 stored and real-

time data. A LOW input level selects real-time data and a

HIGH selects stored data.

Data on the A or B data bus, or both, can be stored in the

internal D flip-flops by LOW-to-HIGH transitions at the appro-

priate clock pins (CPAB or CPBA), regardless of the select or

enable control pins.

– VOL = 0.3V (typ.)

– Meets or exceeds JEDEC standard 18 specifications

– Product available in Radiation Tolerant and Radiation

Enhanced versions

– Military product compliant to MIL-STD-883, Class B

and DESC listed (dual marked)

– Available in DIP, SOIC, SSOP, QSOP, TSSOP,

CERPACK and LCC packages

• Features for FCT646T/648T/652T:

– Std., A, C and D speed grades

– High drive outputs (-15mA IOH, 64mA IOL)

– Power off disable outputs permit “live insertion”

• Features for FCT2646T/2652T:

The FCT26xxT have balanced drive outputs with current

limiting resistors. This offers low ground bounce, minimal

undershoot and controlled output fall times-reducing the need

for external series terminating resistors. FCT2xxxT parts are

plug-in replacements for FCTxxxT parts.

– Std., A, and C speed grades

– Resistor outputs (-15mA IOH, 12mA IOL Com.)

(-12mA IOH, 12mA IOL Mil.)

– Reduced system switching noise
