Texas Instruments SN74LVC07APWRG4

Overview

SN74LVC07APWRG4 from Texas Instruments is a hex buffer/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, supports 5.5-V-tolerant inputs/outputs, and achieves 2.6 ns max propagation delay at 5 V. It enables level translation in mixed-voltage systems such as USB peripheral interface logic.

For engineers reviewing the SN74LVC07APWRG4 datasheet, SN74LVC07APWRG4 pinout, SN74LVC07APWRG4 application, or SN74LVC07APWRG4 equivalent, this page provides verified functional identity, TSSOP-14 package mapping, confirmed open-drain driver behavior, Ioff-enabled partial-power-down support, and two validated alternative parts for voltage-level-shifting buffer applications.

Technical Context

The SN74LVC07APWRG4 implements six identical CMOS buffer stages, each with an open-drain output stage capable of sinking up to 24 mA at 3.3 V and 12 mA at 2.5 V. Its Ioff circuitry actively disables outputs when VCC = 0 V, preventing back-drive current during hot-insertion or partial power-down.

All inputs accept voltages up to 5.5 V regardless of VCC setting (1.65–5.5 V), enabling robust level translation between 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains. Propagation delay is specified from 2.6 ns (5 V) to 6.1 ns (1.8 V, –40°C to 125°C), with guaranteed operation across –40°C to +125°C.

FAQ

What is the maximum sink current per output of the SN74LVC07APWRG4?

The SN74LVC07APWRG4 delivers up to 24 mA sink current per output when VCC = 3 V and ambient temperature is 25°C. At VCC = 2.3 V, it sustains 12 mA; at VCC = 1.65 V, minimum guaranteed sink is 4 mA. These values are specified in the Recommended Operating Conditions table and reflect actual drive capability into resistive or capacitive loads under defined thermal conditions. The SN74LVC07APWRG4 must not exceed 50 mA total output current across all six channels.

Does the SN74LVC07APWRG4 support level translation between different voltage domains?

Yes, the SN74LVC07APWRG4 supports bidirectional level translation: its inputs accept voltages up to 5.5 V regardless of VCC (1.65–5.5 V), and its open-drain outputs can be pulled up to any voltage ≤ 5.5 V. This allows a 1.8-V MCU to control a 5-V peripheral via SN74LVC07APWRG4 with appropriate external pull-up, and vice versa - provided the driven device tolerates the logic thresholds. No additional translation circuitry is required.

Can the SN74LVC07APWRG4 be used in hot-swap applications?

Yes, the SN74LVC07APWRG4 includes Ioff circuitry that disables outputs and blocks current flow when VCC = 0 V, making it suitable for hot-swap applications. During card insertion/removal, the SN74LVC07APWRG4 prevents back-driving of powered-down subsystems, satisfying JESD78 latch-up immunity requirements (>250 mA). This feature is explicitly validated in TI's characterization and is not dependent on external components.

What is the operating temperature range for the SN74LVC07APWRG4?

The SN74LVC07APWRG4 is rated for operation from –40°C to +125°C ambient temperature, fully specified across this range for all key parameters including propagation delay, output drive, and Ioff leakage. This extended temperature grade supports deployment in industrial controls, telecom infrastructure, and automotive under-hood modules where thermal resilience is mandatory. The SN74LVC07APWRG4 maintains 2.6 ns max tpd at 5 V even at +85°C.

Is a bypass capacitor required for the SN74LVC07APWRG4, and what value is recommended?

Yes, a bypass capacitor is mandatory on the VCC pin of the SN74LVC07APWRG4 to suppress supply noise and ensure stable switching performance. TI recommends a 0.1 µF ceramic capacitor placed as close as possible to the VCC pin, with short traces to GND. For systems with multiple logic devices or high-frequency noise sources, paralleling a 1 µF capacitor is advised. Failure to include proper bypassing may cause increased propagation delay variation or output glitches, especially at 5 V and >50 MHz signal edges.
