DESCRIPTION:

FEATURES:

TheIDT54/74FCT161T/163T,IDT54/74FCT161AT/163AT

and IDT54/74FCT161CT/163CT are high-speed synchro-

nous modulo-16 binary counters built using an advanced dual

metal CMOS technology. They are synchronously preset-

table for application in programmable dividers and have two

types of count enable inputs plus a terminal count output for

versatility in forming synchronous multi-stage counters. The

IDT54/74FCT161T/AT/CT have asynchronous Master Reset

inputsthatoverrideallotherinputsandforcetheoutputsLOW.

The IDT54/74FCT163T/AT/CT have Synchronous Reset in-

puts that override counting and parallel loading and allow the

outputs to be simultaneously reset on the rising edge of the

clock.

• Std., A and C speed grades

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

• CMOS power levels

• True TTL input and output compatibility

– VOH = 3.3V (typ.)

– VOL = 0.3V (typ.)

• High drive outputs (-15mA IOH, 48mA IOL)

• 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, QSOP, CERPACK and LCC

packages
