Hex D-Type Flip Flop with Clear
The TC74HCT174A is a high speed CMOS 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 device may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. The inputs are compatible with TTL, NMOS and CMOS output voltage levels.
Information signals applied to the D inputs are transferred to the Q outputs on the positive going edge of the clock pulse.
When the CLR input is held low, the Q outputs are in the low logic level independent of the other inputs.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Features
High speed: fmax = 56 MHz (typ.) at VCC = 5 V Low power dissipation: ICC = 4 μA (max) at Ta = 25°C Compatible with TTL outputs: VIH = 2.0 V (min)
VIL = 0.8 V (max) Wide interfacing ability: LSTTL, NMOS, CMOS Output drive capability: 10 LSTTL loads Symmetrical output impedance: |IOH| = IOL = 4 mA (min) Balanced propagation delays: tpLH ∼− tpHL Pin and function compatible with 74LS174
