Descripción general

Description

74FST3257DTR2G is a high-speed CMOS logic IC in the 74FST family. The 3257 designation typically denotes a dual data selector/multiplexer arrangement (two independent multiplexers) used to route data signals. It runs from a single 5 V supply with TTL-compatible inputs and is designed for fast switching with relatively low power. The DTR2G suffix indicates RoHS-compliant packaging (tape-and-reel option). Typical uses include bus data routing, signal multiplexing, and simple address/data selection in digital circuits. For exact function, pinout, timing, enable features, and electrical specs, refer to the manufacturer’s datasheet for this specific variant.

Package

In a 16-pin SOIC package, Tape‑and‑Reel (DTR) version, RoHS compliant (2G).

Pinout

- Pin count: 20 pins (20-pin package, e.g., SOIC/DTR).
- Function: 8-bit bidirectional bus transceiver with tri-state outputs. It provides two 8-bit data buses (A and B) with direction control (DIR) and output enable (OE) to place outputs in high-impedance.

Manufacturer

Manufacturer: STMicroelectronics (ST).
What kind of company: A multinational semiconductor company that designs and manufactures integrated circuits and other electronic components (analog/digital ICs, MEMS, sensors, microcontrollers) for automotive, industrial, consumer, and communications markets. Headquartered in Geneva, Switzerland, with a global presence.

Application

Key application areas for 74FST3257DTR2G:
- High-speed bus transceiver/multiplexer/demultiplexer for data and control lines
- Microprocessor/microcontroller system bus buffering and isolation
- Memory and I/O expansion interfaces
- Level shifting between different supply voltages (TTL/CMOS)
- Backplanes, telecom, instrumentation, and embedded systems needing fast data routing and signal integrity

Equivalent

Are you after pin‑for‑pin substitutes for TI SN74FST3257DTR2G? That device is an octal bus transceiver with 3-state outputs. Direct 1:1 cross‑refs from other vendors are scarce; closest matches are other vendors’ 74FST3257 parts (same family) if available. Please specify the target package (DTR20), voltage, and speed so I can pull precise cross‑references.
