Overview

Description

The MC74HC4851ADTR2G is an 8-bit bidirectional bus transceiver from the 74HC family. It connects two 8-bit data buses (A and B) and can transfer data in either direction under a DIR control, while an output-enable (OE) tri-states both sides when inactive. This makes it suitable for bus sharing, inter‑device communication, and level-shifting/isolation between voltage domains.
Key points:
- 8-bit bidirectional transceiver with tri-state outputs
- Direction control (DIR) and output enable (OE)
- CMOS 2–6 V operation (typical 5 V), fast HC family performance
- RoHS-compliant, Pb-free, in tape-and-reel packaging (ADTR2G)
Typical uses include microprocessor/microcontroller bus interfacing, memory expansion, and interfacing between ASICs/other logic devices where two buses must take turns driving a shared line.

Features

Here are typical features of the MC74HC4851ADTR2G (HC family CMOS device):
- 8-bit bidirectional bus transceiver with 3-state outputs
- Direction control input and separate output-enable (tri-state) control
- Operates from a 2 V to 6 V supply (CMOS 74HC family; 4.5–5.5 V common)
- High-speed CMOS performance (fast propagation/transition times for HC devices)
- TTL/CMOS input-compatible
- Low static/dynamic power consumption
- Bidirectional data flow suitable for bus buffering/isolation
- 3-state outputs allow bus sharing without contention
- Packaging: ADTR2G (tape & reel; RoHS-compliant)
Note: For exact electrical characteristics (voltage levels, current, propagation delays, temperature range), please consult the detailed datasheet.

Package

20-pin SOIC package (D‑SOIC), Tape‑and‑Reel (TR) packaging, RoHS compliant (G).

Pinout

- Pin count: 16 pins (in a 16-pin package).
- Function: MC74HC4851ADTR2G is an 8-channel data selector/multiplexer (one-of-eight). It has eight data inputs, a single common output, three select inputs (and an enable), routing the selected input to the output.

Manufacturer
