概述

Description

SN74HC4852QDRQ1 is a TI 74HC-series device. It provides two independent bidirectional data paths (bus transceivers) with separate direction and enable controls, enabling data transfer between two buses without contention. Each path can be driven in either direction, and outputs are tri-statable when disabled. This makes it useful for bus interfacing, data buffering, and I/O expansion in digital systems.
Key features (typical): CMOS high-speed operation; 2V–6V supply range; TTL-compatible inputs; tri-state outputs; separate direction and enable control inputs; ESD protection; RoHS-compliant packaging (QDRQ1).
Common applications: microcontroller peripherals, memory-mapped I/O, bus interfacing where flexible, controlled data flow between two buses is needed.
Note: For exact pinout, timing, drive strength, and data rate, see the SN74HC4852QDRQ1 datasheet.

Package

The SN74HC4852QDRQ1 is in a 20-pin SOIC (D) package, RoHS-compliant.

Pinout

- Pin count: 20 pins (DIP/SOIC package variants)
- Function: Dual 4‑bit bidirectional bus transceiver with 3‑state outputs (two independent 4‑bit data paths with separate direction and enable controls) for transferring 4-bit data between two buses.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: American multinational technology company and one of the world’s largest semiconductor manufacturers, designing and producing analog and digital integrated circuits (ICs) used in a wide range of electronics.

Application

Common applications include:
- Buffering and expanding microcontroller/data buses to memory and peripherals
- Bidirectional data routing between digital blocks
- Level shifting between voltage domains (e.g., 5V to 3.3V)
- Driving/isolating signals on shared buses (backplanes, interconnects) with tri-state control
- Robust signal conditioning for automotive, industrial control, data acquisition, and embedded systems
Note: exact usage depends on the device’s bus/buffer characteristics.

Equivalent

Direct equivalents are other manufacturers’ 8‑bit bus transceivers in the 74HC family. Examples include:
- Nexperia 74HC4852
- On Semiconductor NC74HC4852
For TTL-input variants use 74HCT4852. For exact cross-reference (package/grade QDRQ1), consult TI’s cross-reference tool.
