IDT54/74FCT163T/AT/CT FAST CMOS SYNCHRONOUS PRESETTABLE BINARY COUNTER MILITARY AND INDUSTRIAL TEMPERATURE RANGES FAST CMOS SYNCHRONOUS PRESETTABLE BINARY COUNTER IDT54/74FCT163T/AT/CT FEATURES: DESCRIPTION: − − − − The FCT163T is a high-speed synchronous modulo-16 binary counter 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 FCT163T has Synchronous Reset inputs 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 ≤1µ A (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 Military product compliant to MIL-STD-883, Class B and DESC listed (dual marked) Power off disable outputs permit “live insertion” Available in the following packages: • Industrial: SOIC, QSOP • Military: CERDIP, LCC, CERPACK − − − − − FUNCTIONAL BLOCK DIAGRAM P0 P1 P2 P3 PE CEP CET TC CP CP CP D CP CD Q D Q Q0 Q0 DETAIL A DETAIL A DETAIL A Q1 Q2 Q3 DETAIL A SR Q0 MILITARY AND INDUSTRIAL TEMPERATURE RANGES AUGUST 2000 1 c 1999 Integrated Device Technology, Inc.
