Quad D-Type Flip-Flop with Reset
Features
Description
• Common Clock and Asynchronous Reset on Four
D-Type Flip-Flops
The Harris CD74HC175 and CD74HCT175 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.

• Positive Edge Pulse Triggering
• Complementary Outputs
• Buffered Inputs
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.
