概述

Description

SN74HC4852PWR is an octal buffer/driver in the TI 74HC logic family. It provides eight data paths that buffer and drive signals, with tri‑state outputs controlled by enable inputs, allowing you to isolate and multiplex bus lines or level‑shift between domains.
Key points:
- 8 noninverting buffers with enable control (commonly two enables that tri‑state all outputs when disabled).
- CMOS 74HC family: typical supply range 2V–6V (often 5V, with good bus performance at standard speeds).
- PWR suffix usually denotes a PowerPAD/thermally enhanced package variant.
- Suitable for buffering microcontroller/peripheral data buses, distributing signals to multiple devices, or isolating buses.
For exact pinout, truth table, propagation delays, current limits, and package options, consult the SN74HC4852PWR datasheet. If you’re unsure which variant you need, TI’s datasheet will confirm the enable logic, voltage ranges, and package—essential for reliable interfacing.

Features

SN74HC4852PWR features (concise):
- Two 4-bit bidirectional bus transceivers (8 I/O lines total: A1–A4 and B1–B4)
- Separate direction control for each channel (DIR1, DIR2)
- Separate output enable for each channel (OE1, OE2) – outputs go high-impedance when not enabled
- Active-low enables (3-state outputs when enabled)
- Operating voltage: 2V to 6V (CMOS HC family)
- High-speed CMOS performance with low static power
- Available in PowerPAD (PWR) package for improved thermals
- Suitable for interfacing data buses, microprocessors, and backplanes

Package

A 20‑pin PowerPAD-style package (20‑lead TSSOP/SOP with an exposed pad).

Pinout

- Pin count: 16 pins (standard 16-pin package in SN/SSOP/DIP form factors).
- Function: An 8-bit bidirectional bus transceiver (two 4-bit sections) with direction and enable control, used to connect two buses and transfer data in either direction under control.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: TI is an American multinational semiconductor company that designs and manufactures a broad range of integrated circuits and related electronic components (analog, digital, mixed-signal ICs, processors, sensors, etc.).

Application

SN74HC4852PWR is a high-speed CMOS buffer/driver with tri-state outputs used for bus interfacing. Applications: buffering or level-shifting signals between microcontrollers/ASICs and peripherals; bidirectional data/address bus expansion and data routing; inter-board or backplane data distribution; reducing load and improving signal integrity; memory, display, and peripheral interfaces in embedded systems.

Equivalent

I need the exact function of SN74HC4852PWR to give precise equivalents. If it’s an octal bidirectional bus transceiver, common cross-refs include 74HC245/74HCT245 (and equivalents from Nexperia, Onsemi, Renesas). For an exact vendor cross-reference, use TI’s cross-reference tool or share the device’s function, package and speed grade.
