Description

The ’HC175 and ’HCT175 are high speed Quad D-type Flip-

Flops with individual D-inputs and Q, Q complementary

outputs. The devices are fabricated using silicon gate CMOS

technology. They have the low power consumption

advantage of standard CMOS ICs and the ability to drive 10

LSTTL devices.

Information at the D input is transferred to the Q, Q outputs on

the positive going edge of the clock pulse. All four Flip-Flops

are controlled by a common clock (CP) and a common reset

(MR). Resetting is accomplished by a low voltage level

independent of the clock. All four Q outputs are reset to a

logic 0 and all four Q outputs to a logic 1.
