74HCT112PW,112

Overview

The Nexperia 74HCT112PW,112 is a dual negative-edge triggered JK flip-flop featuring asynchronous active-low set and reset inputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports input levels compatible with TTL standards. The device provides complementary Q and nQ outputs for each flip-flop circuit. It is housed in a 16-TSSOP surface-mount package and is specified for operation across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Dual negative-edge triggered JK flip-flops with individual J and K inputs
• Asynchronous active-low set and reset inputs operating independently of the clock
• Complementary Q and nQ outputs provided for each flip-flop
• Schmitt-trigger action on the clock input for tolerance to slow rise and fall times

Applications

• Digital state storage and memory elements
• Frequency division circuits
• Shift register construction
• Synchronous logic control systems

Procurement Notes

Verify current production status as this component may be subject to discontinuation notices. Confirm package variant compatibility and check for official replacement part numbers before finalizing design specifications. Ensure supply chain sources provide valid authenticity documentation.

Selection Notes

Select this component when dual independent JK flip-flops with asynchronous control are required. The HCT series ensures TTL compatibility while maintaining CMOS performance. Verify that the 16-TSSOP package fits the PCB layout constraints and thermal requirements of the target application environment.
