MC74HCT595ADTR2G

MC74HCT595ADTR2G is an 8-bit serial‑in, parallel‑out shift register with a storage (latch) register and tri‑state outputs. It lets you clock in data (DS) on SH_CP, shifts bits on each clock, and then transfer the byte to the output register with ST_CP (latch). OE enables/disables the outputs; MR clears the registers asynchronously. It also provides a Q7’ serial output for cascading multiple devices. It belongs to the 74HCT family (high‑speed CMOS with TTL‑compatible inputs) and operates from a 4.5–5.5 V supply. Applications include expanding microcontroller I/O, LED displays/LED matrices, and other parallel-output needs; you can cascade several devices to increase total bits. The ADTR2G suffix indicates RoHS-compliant, tape‑and‑reel packaging in a 16‑pin package (SOIC/D‑style).

Note: 74HC595 is CMOS (not TTL-level) and may substitute only in some cases when TTL thresholds aren’t critical. Packaging variants (D, N, DW) vary by vendor.

Key features of MC74HCT595ADTR2G:
- 8-bit serial-in, parallel-out shift register with a separate storage/latch register and 3-state outputs (Q0–Q7).
- Data shifted on the rising edge of SH_CP; ST_CP latches to outputs; MR provides asynchronous reset.
- OE (output enable) is active-low for tri-state outputs; Q7’ serial out for daisy-chaining.
- TTL-compatible inputs; operates at 4.5 V to 5.5 V (HCT levels).
- Wide temperature range (-40°C to 125°C) and RoHS-compliant packaging (ADTR2G, tape & reel).
- Ideal for LED displays and bus-expansion applications; easy cascading via Q7’ output.
