They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The output terminal ( CO/ZD ) goes to an active low state when the down count reaches zero. Since the TC74HC40102A is designed as a BCD counter, programming up to 99 counts is possible. The TC74HC40103A, with its 8-bit binary construction, can be set to provide up to 255 counts. Both devices have Inhibit Clock ( CI/CE ), Asynchronous Preset Control ( APE ), Synchronous Preset ( SPE ) and Clear Control ( CLR ) inputs for setting the counter to the maximum counting mode. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features • High speed: fmax 40 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 40102B, 40103B Pin Assignment TC74HC40102AP, TC74HC40103AP TC74HC40102AF, TC74HC40103AF Weight DIP16-P-300-2.54A : 1.00 g (typ.) SOP16-P-300-1.27A : 0.18 g (typ.) |
