CD74AC112M96G4

Overview

The CD74AC112M96G4 is a dual JK-type negative-edge-triggered flip-flop manufactured by Texas Instruments. It operates within a supply voltage range of 1.5V to 5.5V and features set (preset) and reset functions. The device supports a maximum clock frequency of 100 MHz and delivers output currents of 24mA for both high and low states. It exhibits a typical propagation delay of 10.3ns at 5V with a 50pF load, while maintaining a static current of 4µA. Packaged in a 16-SOIC surface-mount format, it functions reliably across an industrial temperature range of -55°C to 125°C.

Feature Summary

• Dual JK-type flip-flops with negative-edge triggering
• Integrated set (preset) and reset control inputs
• High-speed operation up to 100 MHz clock frequency
• Complementary outputs with 24mA drive capability

Applications

• Parallel-to-serial data conversion circuits
• Frequency division and counting logic
• Shift register implementations
• State machine design and control logic

Procurement Notes

Verify the G4 suffix indicates lead-free composition and RoHS compliance. Confirm the M96 package designation matches the required 16-SOIC footprint dimensions. Ensure the AC series logic level compatibility aligns with system voltage requirements. Check for moisture sensitivity level 1 status if reflow soldering is planned. Validate that the operating temperature range meets environmental specifications.

Selection Notes

Select this component when dual independent JK flip-flops are required in a compact surface-mount package. The AC series offers faster switching speeds compared to standard HC logic families. Consider the 1.5V minimum supply voltage for low-power applications. Verify input capacitance and output drive strength against load requirements. Ensure the negative-edge trigger characteristic fits the timing architecture.

Part Context

This part belongs to the Texas Instruments 74AC family of high-speed CMOS logic devices. The base model CD74AC112 defines the dual JK flip-flop functionality. The M96 suffix specifies the 16-pin SOIC package variant. The G4 suffix denotes lead-free packaging compliant with environmental directives. This series provides performance enhancements over previous generation logic families.

Replacement Considerations

CD74AC112N: PDIP-16 through-hole equivalent. SN74AC112D: Standard SOIC-16 without G4 suffix. CD74HC112M96: HC series alternative with slower speed but similar pinout.
