SN74AC74PWRE4

Flip Flops Overview

The SN74AC74PWRE4 is a dual positive-edge-triggered D-type flip-flop from the Texas Instruments 74AC logic family. It operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 160 MHz. The device features low static current consumption of 2 µA and provides complementary outputs with drive capabilities of ±24 mA. Propagation delay is specified at 6 ns at 5 V with 50 pF load. It is housed in a 14-TSSOP package and functions across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Dual positive-edge-triggered D-type flip-flops with set and reset functionality
• High-speed operation supporting up to 160 MHz clock frequencies
• Low static power consumption characteristic of AC logic series
• Complementary outputs providing strong drive capability

Flip Flops Applications

• Parallel data storage and transfer systems
• Shift register implementations
• Timing and control circuitry
• State machine design

Flip Flops Procurement Notes

Verify the exact part number SN74AC74PWRE4 against manufacturer datasheets to confirm pinout compatibility and electrical specifications. Ensure the TSSOP-14 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status for your specific region regulations. Check for any recent product change notices that may affect assembly or sourcing parameters.

Flip Flops Selection Notes

Select this component when dual independent D-type flip-flops are required in a compact surface-mount package. The 74AC series offers faster switching speeds compared to standard 74LS equivalents while maintaining CMOS input characteristics. Consider the 2 V to 6 V operating range for flexibility in various logic voltage domains. Verify that the 160 MHz maximum frequency meets your system timing requirements.

Flip Flops Part Context

This device belongs to the Texas Instruments 74AC (Advanced CMOS) logic family, designed for high-speed digital applications. The 74AC series provides performance improvements over earlier 74HC devices while maintaining similar pinouts for many functions. The 'E4' suffix indicates lead-free construction compliant with RoHS directives. The PWRE4 designation specifically identifies the TSSOP-14 tape-and-reel packaging variant.

Flip Flops Replacement Considerations

SN74AC74PWR is the non-rohs3 equivalent without the E4 suffix. SN74AC74PWLE4 is available in a smaller LSSOP package. SN74AC74NSRE4 offers the same function in a 14-SOIC package. SN74AC74DBRE4 provides the same function in a 14-SSOP package.
