DESCRIPTION

The M74HC377 is an high speed CMOS OCTAL D TYPE FLIP FLOP fabricated with silicon gate C2MOS technology. Information at the D inputs meeting the setup time requirements is transferred to the Q outputs on the positive going edge of the clock pulse if the enable input Gis low. Clock triggering occurs at a particular voltage level and is not directly relatedto the transition time of the positive going pulse. When the clock input is at either the high or low level, the D input signal has no effect at the output. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

■ HIGH SPEED : fMAX= 66 MHz (TYP.) at VCC= 6V

■ HIGH NOISE IMMUNITY: VNIH= VNIL= 28 VCC(MIN.)

■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL= 4mA (MIN)

■ BALANCED PROPAGATION DELAYS: tPLH ?tPHL

■ WIDE OPERATING VOLTAGE RANGE: VCC(OPR) = 2V to 6V

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 377
