Texas Instruments SN74LVC1G58DRY2

Overview

SN74LVC1G58DRY2 from Texas Instruments is a configurable multiple-function logic gate operating from 1.65 V to 5.5 V, supporting AND, OR, NAND, NOR, XOR, inverter, and noninverter functions via three input pins (In0–In2). It delivers 6.3 ns max propagation delay at 3.3 V, ±24 mA output drive, and Schmitt-trigger inputs with hysteresis for noise immunity. Used in voltage-level translation and reconfigurable signal conditioning in portable power management circuits.

For engineers reviewing the SN74LVC1G58DRY2 datasheet, SN74LVC1G58DRY2 pinout, SN74LVC1G58DRY2 application, or SN74LVC1G58DRY2 equivalent, key selection criteria include its 6-pin SON (DRY) package, Ioff support for live insertion, 10 µA max ICC, and configurable logic mapping without external components.

Technical Context

The SN74LVC1G58DRY2 implements a 3-input lookup table architecture where In0–In2 select one of eight output states per the function table. Its Schmitt-trigger inputs provide distinct VT+ (e.g., 1.5 V at 3 V VCC) and VT– (e.g., 0.84 V at 3 V VCC) thresholds, enabling robust noise rejection in slow-rising or noisy environments.

It supports partial-power-down via Ioff circuitry that disables outputs when VCC = 0 V, preventing back-drive current. All inputs tolerate up to 5.5 V regardless of VCC, allowing down-translation from higher-voltage domains into 1.65–5.5 V logic systems.

FAQ

What logic functions does the SN74LVC1G58DRY2 support?

The SN74LVC1G58DRY2 supports eight logic configurations determined by its three inputs (In0–In2): AND, OR, NAND, NOR, XOR, inverter, noninverter, and NAND with both inputs inverted. Each configuration maps directly to a row in the device's function table, enabling flexible logic synthesis without external components. The SN74LVC1G58DRY2 does not require programming or configuration registers - behavior is purely combinational and static.

Does the SN74LVC1G58DRY2 support level translation between different voltage domains?

Yes, the SN74LVC1G58DRY2 supports bidirectional level translation: inputs accept voltages up to 5.5 V independent of VCC (which can be as low as 1.65 V), and outputs swing rail-to-rail between GND and VCC. This allows interfacing 5 V sensors or legacy peripherals with 1.8 V or 3.3 V microcontrollers. The SN74LVC1G58DRY2 achieves this without external resistors or translators, simplifying design and reducing board area.

What is the purpose of the Schmitt-trigger inputs on the SN74LVC1G58DRY2?

The Schmitt-trigger inputs on the SN74LVC1G58DRY2 provide hysteresis (ΔVT ≥ 0.53 V at 3 V VCC), ensuring clean, bounce-free switching on slow-rising or noisy signals such as mechanical switches, thermistors, or unfiltered sensor outputs. This eliminates the need for external RC filters or debouncing firmware. The SN74LVC1G58DRY2's VT+ and VT– thresholds are guaranteed across temperature and voltage, making it ideal for industrial and automotive edge-node applications.

Can the SN74LVC1G58DRY2 be used in hot-swap or partial-power-down systems?

Yes, the SN74LVC1G58DRY2 includes Ioff circuitry that disables outputs when VCC = 0 V, limiting off-state current to ±10 µA and preventing damaging back-current from live backplanes or powered subsystems. This makes the SN74LVC1G58DRY2 suitable for modular systems requiring live insertion, such as field-replaceable I/O cards or docking stations, without risk of latch-up or bus contention.

What is the thermal performance of the SN74LVC1G58DRY2 in its DRY package?

The SN74LVC1G58DRY2 in the 6-pin SON (DRY) package features an exposed thermal pad and achieves a θJA of 123°C/W, significantly better than comparable SC70 or SOT-23 packages. This enables reliable operation at full output drive (±24 mA) up to +125°C ambient when mounted on 2-layer PCBs with adequate copper pour. The SN74LVC1G58DRY2's thermal efficiency supports use in sealed enclosures or high-density layouts where airflow is restricted.
