Integrated Device Technology, Inc. FAST CMOS SYNCHRONOUS PRESETTABLE BINARY COUNTERS DESCRIPTION: IDT54/74FCT161T/AT/CT IDT54/74FCT163T/AT/CT Features : - - - - Std., A and C speed grades Low input and output leakage ≤1µA (max.) CMOS power levels True TTL input and output patibility - VOH = 3.3V (typ.) - VOL = 0.3V (typ.) High drive outputs (-15m A IOH, 48m A IOL) Meets or exceeds JEDEC standard 18 specifications Product available in Radiation Tolerant and Radiation Enhanced versions Military product pliant to MIL-STD-883, Class B and DESC listed (dual marked) Available in DIP, SOIC, QSOP, CERPACK and LCC packages - - - - - The IDT54/74FCT161T/163T, IDT54/74FCT161AT/ 163AT and IDT54/74FCT161CT/163CT are high-speed synchronous modulo-16 binary counters built using an advanced dual metal CMOS technology. They are synchronously presettable 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 inputs that override all other inputs and force the outputs LOW. The IDT54/74FCT163T/AT/CT have Synchronous Reset inputs that override counting and parallel loading and allow the outputs to be simultaneously reset on the rising edge of the clock.
