Product details

Dual JK flip-flop for 5V logic systems

The SN74ALS112AD is a dual 1-bit JK-type flip-flop from Texas Instruments' 74ALS family, clocked at 30 MHz with negative-edge triggering and complementary outputs.

Timing and propagation delay

Maximum propagation delay is 19 ns at 5V into a 50 pF load — the limiting path for a 30 MHz clock is the clock-to-output delay, not the toggle rate.

The 1.27 mm pitch is layout-friendly for two-layer boards — no via-in-pad required. Tube packaging is standard for prototype and low-volume builds; the same die is also available in tape-and-reel under alternate order codes.
