概述

Description

The SN74HC126DR is a quad buffer/driver with three-state outputs from Texas Instruments, designed for high-speed applications. It features four independent non-inverting buffers capable of driving heavily loaded lines. The device is part of the 74HC family, which operates at high speed and offers low power consumption.
Key specifications include a supply voltage range of 2V to 6V, with a typical propagation delay of 10 ns at 5V. Each output can drive up to 15 mA at high drive conditions. The SN74HC126DR also supports TTL logic levels, making it compatible with various digital circuits.
The device features a three-state output, allowing multiple devices to share a common bus without interference. It is packaged in a Shrink Small Outline (SSOP) format, designated as "DR," suitable for surface mounting. Applications include bus-oriented systems, data communications, and general-purpose signal buffering.

7. Temperature Range: Operates within a wide temperature range, typically -40°C to 125°C.
8. Packaging: Available in a 14-TSSOP package, facilitating compact designs.
These features make the SN74HC126DR suitable for applications in data routing, signal buffering, and interfacing in various electronic systems.

Package

The SN74HC126DR is packaged in a 14-pin SOIC (Small Outline Integrated Circuit) form factor. This surface-mount package is designed for compact applications and features a wide range of operating temperatures.

Pinout

The SN74HC126DR is a quad buffer/driver with three-state outputs and is part of the Texas Instruments 74HC series logic family. It features a 14-pin dual in-line package (DIP) configuration.
Pin Count: 14 pins
Functions:
- The device includes four independent buffers/drivers (A, B, C, D) for input signals.
- Each buffer has a three-state output (Y) that can be enabled or disabled via an output enable pin (OE).
- The function can be summarized as follows:
- Inputs (A1, A2, A3, A4) correspond to outputs (Y1, Y2, Y3, Y4).
- Outputs are enabled when the corresponding OE pin is low (active low).
- When OE is high, the outputs are in a high-impedance state.
Typical use cases include signal buffering and driving, as well as interfacing between different logic levels.
