CD74HC574M Overview
Key Specifications
Package: SOIC
Mount Type: Surface Mount
Pins: 20
Max Voltage (typical range): 6 V
Description
The ’HC374, ’HCT374, ’HC574, and ’HCT574 are octal D-type flip-flops with 3-state outputs and the capability to drive 15 LSTTL loads. The eight edgetriggered flip-flops enter data into their registers on the LOW to HIGH transition of clock (CP).
Key Features
- Buffered inputs
- Common three-state output enable control
- Three-state outputs
- Bus line driving capability
- Typical propagation delay (clock to Q) = 15 ns at VCC = 5 V, CL = 15 pF, TA = 25℃
- Fanout (over temperature range) – Standard outputs: 10 LSTTL loads – Bus driver outputs: 15 LSTTL loads
- Wide operating temperature range: –55℃ to 125℃
- Balanced propagation delay and transition times
- Significant power reduction compared to LSTTL Logic ICs
- HC types – 2-V to 6-V operation – High noise immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5 V
