Overview
TC74HC377AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC377AP, TC74HC377AF Octal D-Type Flip-Flop The TC74HC377A is a high speed CMOS OCTAL D-TYPE FLIP-FLOP fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.
This 8-bit D-type flip-flop is controlled by a clock input (CK) and an output enable input ( G ).
The signal level applied to the D inputs are transferred to Q outputs during the positive going transition of CK.
When the G is high, the eight outputs are in a high impedance state.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Features • High speed: fmax = 73 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 74LS377 Pin Assignment TC74HC377AP TC74HC377AF Weight DIP20-P-300-2.
