Texas Instruments Dual Negative-Edge JK Flip-Flop IC, 16-Pin DIP

Texas Instruments Dual Negative-Edge JK Flip-Flop IC is a dual negative-edge-triggered J-K flip-flop with independent set and reset functions, providing controlled digital logic in a 16-pin DIP package.

Overview

Each flip-flop features independent J, K, Set, Reset and Clock inputs, along with complementary Q and Q-bar outputs. State changes occur on the negative-going transition of the clock pulse, and asynchronous set and reset are accomplished via low-level inputs. The device is built using advanced silicon-gate CMOS technology, delivering high-speed operation equivalent to LSTTL components while maintaining the low power consumption associated with CMOS integrated circuits. It can drive up to 10 LSTTL loads.

Key Features

• High noise immunity: hysteresis on the clock inputs improves noise immunity and allows increased input rise and fall times for stable operation in electrically noisy environments.
• Asynchronous control: independent set and reset inputs provide immediate control over the output state, regardless of the clock signal.
• Efficient power usage: offers significant power reduction compared to traditional LSTTL logic integrated circuits.
• Logic compatibility: the HCT logic family provides direct LSTTL input logic compatibility and CMOS input compatibility, and is pin-for-pin compatible with the standard LS logic family.
• Balanced performance: buffered inputs and balanced propagation delay and transition times contribute to predictable circuit timing.

Package and Mounting

This integrated circuit is supplied in a standard 16-pin Dual In-line Package (DIP), suitable for through-hole PCB assembly. Its pin-for-pin compatibility with LS logic makes it straightforward to upgrade or replace devices in existing designs.

Dimensions and Weight

Width 3.3, depth 1.5 and height 4.3, with a weight of 1.678 gm.
