CD54HCT112F3A

The CD54HCT112F3A from Harris Semiconductor is a dual J-K flip-flop integrated circuit designed for digital logic applications. It utilizes silicon-gate CMOS technology, offering operating speeds comparable to LSTTL parts while maintaining low power consumption. This device features independent J, K, Set, Reset, and Clock inputs, along with Q and Q outputs. State changes occur on the negative-going transition of the clock pulse, and Set/Reset functions are asynchronous, activated by low-level inputs.

The flip-flop is specified for a wide operating temperature range of -55°C to 125°C and operates with a nominal supply voltage of 5V, with a range from 4.5V to 5.5V. It supports a maximum operating frequency of 20MHz. The device offers standard outputs with a fanout of 10 LSTTL loads and bus driver outputs with a fanout of 15 LSTTL loads. The CD54HCT112F3A is packaged in a 16-lead CERDIP with through-hole mounting.

Key electrical characteristics include a typical operating voltage of 5V and a maximum output current of 4mA. The load capacitance is specified at 50pF. The HCT logic family ensures functional and pin compatibility with standard LS logic families, making it suitable for direct integration into existing designs.
