CD74HC597E - Brand New Texas Instruments Shifting Register
-
Description
The CD74HC597E is a high-speed, CMOS silicon gate octal shift register with 3-state parallel outputs. It has a low power consumption and the ability to drive 15 LSTTL devices making it ideal for use in shifting register applications in electronic circuits. The CD74HC597E is a functionally and pin compatible alternative to the 74LS597 shift register.
Specifications and features
• Low power consumption

• Fanout (over temperature range)
- Standard outputs: 10 LSTTL loads
- Bus driver outputs: 15 LSTTL loads
• Typical propagation delay: 12ns at VCC=5V, CL=15pF, TA=25°C (data to output for HC373)
• HC types
- Operation range: 2V to 6V
- High noise immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V
• HCT types
- Operation range: 4.5V to 5.5V
- Direct LSTTL input logic compatibility: VIL = 0.8V (max), VIH = 2V (min)
- CMOS input compatibility: Il ≤1µA at VOL, VOHApplication Scenarios
The CD74HC597E is commonly used in electronic circuits as an octal shift register with 3-state parallel outputs. It can be used in applications where data needs to be serially shifted in and out of a shift register, such as in data storage, data communication, and data multiplexing.
Comparison
