Visão Geral
Description
Each buffer in the SN74LVTH125PWR has a separate output-enable (OE) control, allowing individual outputs to be placed in a high-impedance state, enabling efficient data bus management. The IC is built with Schmitt-trigger action at the inputs, providing increased noise immunity and ensuring stable operation in noisy environments. It is packaged in a compact TSSOP (Thin Shrink Small Outline Package), enhancing its suitability for space-constrained applications.
The SN74LVTH125PWR is particularly used in computing, networking, and telecommunications applications where performance, reliability, and power efficiency are critical. Its robust design and compliance with industry standards make it a versatile choice for engineers and designers.
Equivalent
1. 74LVT125 series from NXP and ON Semiconductor
2. 74LVTH125 series from Fairchild Semiconductor
3. SN74LVC125A series from Texas Instruments
These alternatives are similar in function and performance, providing low-voltage and high-speed operation in digital circuit applications. Always verify the electrical characteristics and pin configurations to ensure compatibility.
Features
1. Low-Voltage and Low-Power Consumption: Operates with a voltage range from 2.7V to 3.6V, making it suitable for low-power applications.
2. Output Drive: Provides high drive capability with outputs that can drive up to 64mA, suitable for driving heavily loaded lines.
3. Bus-Hold Feature: Eliminates the need for pull-up or pull-down resistors by maintaining the last known state of the input if it becomes floating.
4. Overvoltage Tolerant Inputs: Allows for input voltages higher than the supply voltage, up to 5.5V.
5. High-Speed Operation: Supports fast switching speeds due to its advanced CMOS technology.
6. Latch-Up Performance: Exceeds 250mA per JESD 17, enhancing device reliability.
7. Wide Range of Applications: Ideal for use in buffer, driver, or line receiver applications.
8. Packaging: Available in TSSOP package, providing compact design options.
These features make the SN74LVTH125PWR versatile for various digital logic applications in modern electronic systems.
Pinout
The SN74LVTH125PWR comes in a TSSOP (Thin Shrink Small Outline Package) with 14 pins. The pin configuration is as follows:
- Pins 1, 4, 10, 13: Output Enable (OE) inputs for each of the four buffer gates.
- Pins 2, 5, 9, 12: Data Inputs (A) for each buffer.
- Pins 3, 6, 8, 11: Data Outputs (Y) for each buffer.
- Pin 7: Ground (GND).
- Pin 14: Positive Supply Voltage (VCC).
Functionally, each buffer gate is controlled by its respective OE pin. When OE is low, the buffer is enabled, and the input data (A) is transmitted to the output (Y). When OE is high, the output is in a high-impedance state, effectively disconnecting it from the circuit. This allows for bus-oriented applications and signal multiplexing or demultiplexing.
