概要

Description

74HC245PW,118 is an 8-bit bidirectional bus transceiver from the 74HC family. It connects two 8-bit buses (A0–A7 and B0–B7) with a single direction control (DIR) and an active-low output enable (/OE).
- Operation: When /OE is low, data flows in the direction specified by DIR: DIR = 0 transfers A→B; DIR = 1 transfers B→A. When /OE is high, both sides are high-impedance.
- Power: Vcc typically 4.5–5.5 V (can operate from 2–6 V).
- Packaging: PW denotes a plastic DIP 20-pin package.
- Use cases: bus sharing/isolation between devices (microcontrollers, memories, peripherals), where tri-state control is needed to prevent bus contention.
- Notes: Check the datasheet for exact pinout and timing. The “118” is likely a date/lot code and doesn’t affect function.

Features

Key features of 74HC245PW,118:
- 8-bit bidirectional bus transceiver with 3-state outputs
- A and B data buses (A0–A7 and B0–B7)
- Direction control input (DIR): A↔B data flow selection
- Output enable (G): tri-states both ports when asserted
- CMOS technology, high speed, low power
- Supply voltage: typically 2 V to 6 V (5 V CMOS common)
- TTL/CMOS-compatible input thresholds (at applicable Vcc)
- Suitable for bus interfacing, data buffering, and isolation in microprocessor/mmemory systems
- Package: 20-pin plastic package (PW variant) commonly available as DIP/PLASTIC variants
Notes: Always check the exact datasheet for temperature range and packaging options for your specific lot/version.

Package

Plastic DIP (20-pin DIP, 0.3" wide). The “PW” indicates Plastic DIP; “118” is a date/lot code.

Pinout

- Pin count: 20 pins (DIP-20 / SOIC-20).
- Function: 8-bit bidirectional bus transceiver with tri-state outputs. Data can transfer between two buses (A0–A7 and B0–B7) controlled by DIR (direction) and OE (output enable). Used to connect buses while allowing high-impedance when disabled.

Manufacturer

Manufacturer: Nexperia.
Type of company: A Dutch multinational semiconductor company that specializes in discrete components, logic ICs, and MOSFET devices (a spin-off from Philips/NXP).

Application

- 74HC245PW: Octal bidirectional bus transceiver with 3-state outputs. Applications: CPU/memory and CPU/I/O bus buffering, bus isolation, level shifting between logic families, and data-path multiplexing in microprocessor systems.
- 74HC118: Typically a decoder/demultiplexer in the 74HC family. Applications: address/data decoding and device selection in memory-mapped systems, peripheral demultiplexing, display decoding, and simple logic routing.
