MC14043B/D is a CMOS MSI Quad R−S Latches produced by Semiconductor Components Industries, LLC. It has the characteristics of Double Diode Input Protection, Three−State Outputs with Common Enable, Outputs Capable of Driving Two Low−power TTL Loads or One Low−Power Schottky TTL Load Over the Rated Temperature Range, Supply Voltage Range = 3.0 Vdc to 18 Vdc, Pb−Free Packages are Available.
The MC14043B and MC14044B are CMOS MSI quad set‑reset (R‑S) latch devices. Each latch provides an independent Q output, set and reset inputs, and three‑state outputs that share a common enable pin. Unused inputs must be tied to a logic level and unused outputs left open.
Key specifications include a 3.0 V to 18 V supply range, ±10 mA input/output current per pin, 500 mW power dissipation, and operation from –55 °C to +125 °C. The devices are offered in PDIP‑16 and SOIC‑16 packages, with both standard and Pb‑free options, and are suitable for driving low‑power TTL or Schottky TTL loads.
