Features
Description
• Buffered Positive Edge Triggered Clock
The Harris CD74HC174 and CD74HCT174 are edge
triggered flip-flops which utilize silicon gate CMOS circuitry to
implement D-type flip-flops. They possess low power and
speeds comparable to low power Schottky TTL circuits. The
devices contain six master-slave flip-flops with a common
clock and common reset. Data on the D input having the
specified setup and hold times is transferred to the Q output
on the low to high transition of the CLOCK input. The MR
input, when low, sets all outputs to a low state.
• Asynchronous Common Reset
• Fanout (Over Temperature Range)
- Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads
- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
• Wide Operating Temperature Range . . . -55oC to 125oC
• Balanced Propagation Delay and Transition Times
Each output can drive ten low power Schottky TTL
equivalent loads. The CD74HCT174 is functional as well as,
pin compatible to the 74LS174.
• Significant Power Reduction Compared to LSTTL
Logic ICs
• HC Types
- 2V to 6V Operation
- High Noise Immunity: NIL = 30%, NIH = 30% of VCC
at VCC = 5V
Ordering Information
• HCT Types
- 4.5V to 5.5V Operation
- Direct LSTTL Input Logic Compatibility,
VIL= 0.8V (Max), VIH = 2V (Min)
- CMOS Input Compatibility, Il ≤ 1µA at VOL, VOH
