DESCRIPTION
The M74HCT174 is an high speed CMOS HEX D-TYPE FLIP FLOP WITH CLEAR fabricated with silicon gate C2MOS technology.
Information signals applied to D inputs are transferred to the Q output on the positive going edge of the CLOCK (CK) pulse. When the CLEAR (CLR) input is held low, the Q outputs are held low independently of the other inputs.
All inputs are equipped with protection circuits against static discharge and transient excess voltage.
■ HIGH SPEED :
fMAX = 56MHz (TYP.) at VCC = 4.5V
■ LOW POWER DISSIPATION:
ICC =4µA(MAX.) at TA=25°C
■ COMPATIBLE WITH TTL OUTPUTS :
VIH = 2V (MIN.) VIL = 0.8V (MAX)
■ SYMMETRICAL OUTPUT IMPEDANCE:
|IOH| = IOL = 4mA (MIN)
■ BALANCED PROPAGATION DELAYS:
tPLH ≅ tPHL
■ PIN AND FUNCTION COMPATIBLE WITH
74 SERIES 174
