Texas Instruments SN74LVC07APWT

Overview

SN74LVC07APWT from Texas Instruments is a hex buffer and driver IC with six independent open-drain outputs, designed for 1.65 V to 5.5 V operation. It delivers 24 mA sink current per output at 3.3 V, accepts 5.5-V-tolerant inputs, and achieves 2.6 ns propagation delay at 5 V - enabling level translation, wired-OR logic, and LED driving in mixed-voltage systems.

For engineers reviewing the SN74LVC07APWT datasheet, SN74LVC07APWT pinout, SN74LVC07APWT application, or SN74LVC07APWT equivalent, key selection criteria include open-drain drive strength, Ioff-enabled partial-power-down capability, 5.5-V input tolerance across VCC range, and TSSOP-14 package compatibility with high-density PCB layouts.

Technical Context

The SN74LVC07APWT implements six identical CMOS buffer stages, each with an open-drain output stage capable of sinking up to 24 mA at 3.3 V. Its Ioff circuitry actively disables all outputs when VCC = 0 V, preventing back-drive current and supporting live insertion in hot-swap systems.

All inputs are overvoltage tolerant to 5.5 V regardless of VCC setting (1.65–5.5 V), enabling bidirectional voltage translation between 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains without external components. Propagation delay remains ≤3.1 ns over –40°C to +125°C at 5 V.

FAQ

What is the maximum sink current per output of the SN74LVC07APWT?

The SN74LVC07APWT delivers up to 24 mA sink current per output at VCC = 3.3 V and TA = 25°C. At 5 V, it sustains 24 mA with VOL ≤ 0.55 V. This rating applies individually to each of the six open-drain outputs, with total device current limited to ±50 mA across all channels.

Does the SN74LVC07APWT support partial-power-down operation?

Yes, the SN74LVC07APWT features Ioff circuitry that disables all outputs when VCC = 0 V, limiting Ioff current to ±10 µA. This prevents back-driving current from live inputs or outputs into a powered-down device - essential for hot-swap, power-gating, and mixed-rail system architectures.

Can the SN74LVC07APWT translate between 1.8-V and 5-V logic levels?

Yes, the SN74LVC07APWT accepts input voltages up to 5.5 V regardless of VCC setting (1.65–5.5 V), and its open-drain outputs can be pulled up to any voltage ≤5.5 V. When VCC = 1.8 V and outputs are pulled to 5 V, it functions as a reliable unidirectional level shifter from 1.8-V control logic to 5-V peripherals.

What is the operating temperature range of the SN74LVC07APWT?

The SN74LVC07APWT is rated for continuous operation from –40°C to +125°C ambient temperature. This extended range is validated across all electrical specifications including propagation delay, output drive, and Ioff performance - making it suitable for under-hood automotive, industrial motor control, and outdoor telecom equipment.

Is a pull-up resistor required for SN74LVC07APWT outputs?

Yes, every SN74LVC07APWT output is open-drain and requires an external pull-up resistor to define the logic-high voltage level and provide current sourcing. The resistor value depends on rise time requirements and load capacitance; typical values range from 1 kΩ (for fast edges into light loads) to 10 kΩ (for low-power standby states).
