SN74LVT125DR

The SN74LVT125DR is a non-inverting buffer IC manufactured by Texas Instruments. Designed for low-voltage 3.3V VCC operation, it also provides a TTL interface for a 5V system environment. This device features independent line drivers with 3-state outputs, which enter a high-impedance state when the output-enable input is high.

Key electrical characteristics include an operating voltage range of 2.7V to 3.6V and output currents of 32mA or 64mA. It supports mixed-mode signal operation and unregulated battery operation down to 2.7V. The typical output ground bounce is less than 0.8V at 3.3V VCC and 25°C. The device also supports partial-power-down mode operation using Ioff circuitry.

For reliability, the SN74LVT125DR includes active bus-hold circuitry on data inputs, eliminating the need for external pullup resistors. Its latch-up performance exceeds 500mA per JEDEC standard JESD-17, and ESD protection exceeds 2000V for the Human-Body Model (A114-A) and 200V for the Machine Model (A115-A).

The SN74LVT125DR is supplied in a 14-pin SOIC package, suitable for surface mounting. The operating temperature range is -40°C to 85°C. Standard packaging options include tubes of 50 units or tape and reels of 2500 units.
