Product Overview: 74HCT109PW by NXP Semiconductors

The 74HCT109PW from NXP Semiconductors is a high-speed Si-gate CMOS device that is pin compatible with Low-power Schottky TTL (LSTTL). This dual positive edge-triggered JK flip-flop integrated circuit is designed for robust performance in a wide range of applications. It is part of the 74HCT family, which is known for its high noise immunity and low power consumption.

Key Features

• Logic Type: Dual JK Flip-Flop with Set and Reset
• Operating Voltage: 4.5 V to 5.5 V
• Output Current: -8 mA / +8 mA
• Trigger Type: Positive-edge
• Package: TSSOP16 (Thin Shrink Small Outline Package)
• Temperature Range: -40°C to +125°C
• Logic Family: HCT

Product Description

The 74HCT109PW is equipped with two identical, independent JK flip-flops with individual J, K, clock (CP), set (SD), and reset (RD) inputs, and complementary Q and Q outputs. The set and reset are asynchronous active LOW inputs and operate independently of the clock input. The JK design allows each flip-flop to operate as a toggle flip-flop by tying both inputs to HIGH.

With its fast propagation delay and edge-triggered clock inputs, the 74HCT109PW ensures reliable operation in high-speed systems. The device's standard TSSOP16 packaging makes it suitable for surface-mounted design, offering a compact solution for space-constrained applications.

For designers looking for TTL compatibility with the added benefits of CMOS technology, such as lower power dissipation and higher speeds, the 74HCT109PW is an excellent choice. Its robustness is further ensured by the wide operating temperature range, making it suitable for industrial and automotive environments, as well as consumer electronics.

Applications
