1 / 15 page TC74HC161,163AP/AF/AFN 2007-10-01 1 TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC161AP,TC74HC161AF,TC74HC161AFN TC74HC163AP,TC74HC163AF,TC74HC163AFN Synchronous Presettable 4-Bit Counter TC74HC161AP/AF/AFN Binary, Asynchronous Clear TC74HC163AP/AF/AFN Binary, Synchronous Clear The TC74HC161A and 163A are high speed CMOS BINARY PRESETTABLE COUNTERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The CK input is active on the rising edge. Both LOAD and CLR inputs are active on low logic level. Presetting of their IC’s is synchronous to the rising edge of CK. The clear function of the TC74HC163A is synchronous to CK, while the TC74HC161A is cleared asynchronously. Two enable inputs (ENP and ENT) and CO are provided to enable easy cascading of counters, which facilitates easy implementation of n-bit counters without using external gates. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features • High speed: fmax = 63 MHz (typ.) at VCC = 5 V • Low power dissipation: ICC = 4 μA (max) at Ta = 25°C • High noise immunity: VNIH = VNIL = 28% VCC (min) • Output drive capability: 10 LSTTL loads • Symmetrical output impedance: |IOH| = IOL = 4 mA (min) • Balanced propagation delays: tpLH ∼− tpHL • Wide operating voltage range: VCC (opr) = 2 to 6 V • Pin and function compatible with 74LS161, 163 Pin Assignment Note: xxxFN (JEDEC SOP) is not available in Japan.
