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
