NXP 74HC237D,653 Latch-Enabled 3-to-8 Decoder Demux in SOIC‑16

The Nexperia 74HC237D,653 combines a 3‑to‑8 decoder/demultiplexer with a 3‑bit storage latch, offering precise control in digital logic routing and memory applications. When Latch Enable (LE) is LOW, address inputs (A0–A2) transparently drive the decoder; switching LE HIGH locks in the last value until LE toggles again. Dual output enables (E1, active low; E2, active high), allowing independent control, making it ideal for bus-oriented designs or cascading decoders.

Product Standout Features and Benefits

• Low‑Power CMOS with excellent noise immunity, perfect for modern low-noise, high-efficiency systems.
• JEDEC-compliant logic ensures predictable performance, including strong latch-up (>100 mA) and ESD protection for rugged reliability.
• With a ±5.2 mA output current capability, 500 mW power dissipation, and operational capability up to +125 °C, it is suited for demanding industrial environments.
• The compact SOIC-16 Package (3.9 mm width) enables space-efficient surface mounting in high-density PCBs.

Usage Information

This decoder is ideal for memory decoding, data routing, bus interface, and address strobe applications in various fields, including telecommunications, embedded systems, industrial automation, and test equipment. The combination of latch functionality with flexible output control (E1/E2) ensures smooth, glitch-free operation in dynamic logic configurations.
