Texas Instruments SN74LVC1G58DCKRE4

Overview

SN74LVC1G58DCKRE4 from Texas Instruments is a configurable single-gate logic IC supporting AND, OR, NAND, NOR, XOR, inverter, and noninverter functions via three input pins (In0–In2) with Schmitt-trigger inputs, 1.65–5.5 V operation, 6.3 ns max propagation delay at 3.3 V, and ±24 mA output drive - used in level translation, signal conditioning, and flexible logic routing in space-constrained portable electronics.

For engineers reviewing the SN74LVC1G58DCKRE4 datasheet, SN74LVC1G58DCKRE4 pinout, SN74LVC1G58DCKRE4 application, or SN74LVC1G58DCKRE4 equivalent, key selection criteria include its 6-pin SC70 package, Ioff-enabled live insertion support, hysteresis-based noise immunity (ΔVT = 0.53–1.11 V), 10 µA max ICC, and compatibility with mixed-voltage systems requiring down-translation to VCC.

Technical Context

The SN74LVC1G58DCKRE4 implements a 3-input lookup table architecture where In2/In1/In0 select one of eight output states per the function table, enabling reconfigurable combinational logic without external programming. Its Schmitt-trigger inputs provide distinct VT+ (1.5–2.74 V) and VT– (0.35–2.29 V) thresholds for robust noise rejection in noisy environments.

It features Ioff circuitry that disables outputs during partial power-down, preventing back-drive current when VCC = 0 V, and supports live insertion in hot-swap applications. All inputs tolerate up to 5.5 V regardless of VCC, enabling seamless interfacing between 1.8 V, 2.5 V, 3.3 V, and 5 V domains.

FAQ

What logic functions does the SN74LVC1G58DCKRE4 support?

The SN74LVC1G58DCKRE4 supports eight configurable logic functions: AND, OR, NAND, NOR, XOR, inverter, noninverter, and 2-input NAND with both inputs inverted. These are selected by applying specific high/low states to its three input pins (In0, In1, In2) per the function table in the datasheet. Each configuration is static - no dynamic reprogramming is required once pins are set.

Does the SN74LVC1G58DCKRE4 support level translation between different supply voltages?

Yes, the SN74LVC1G58DCKRE4 supports down-translation: its inputs accept voltages up to 5.5 V while operating from a VCC as low as 1.65 V. This allows direct interfacing between 5 V sensors and 1.8 V or 3.3 V microcontrollers without external level shifters - a key capability confirmed in the "Supports Down Translation to VCC" feature list and electrical characteristics table.

What is the purpose of the Ioff feature in the SN74LVC1G58DCKRE4?

The Ioff feature in the SN74LVC1G58DCKRE4 disables output drivers when VCC = 0 V, limiting off-state leakage to ±10 µA. This prevents damaging back-current flow through the device during hot insertion, partial power-down, or system maintenance - critical for backplane and modular electronics where boards may be swapped while other sections remain powered.

How does the Schmitt-trigger input improve noise immunity in the SN74LVC1G58DCKRE4?

The SN74LVC1G58DCKRE4 features asymmetric input thresholds: VT+ (1.5–2.74 V) for rising edges and VT– (0.35–2.29 V) for falling edges, yielding hysteresis (ΔVT) of 0.53–1.11 V. This prevents multiple toggles on slow or noisy signals - such as mechanical switch bounce or EMI-coupled sensor lines - ensuring clean, chatter-free logic transitions without external filtering.

Which package type is used for the SN74LVC1G58DCKRE4, and what are its dimensions?

The SN74LVC1G58DCKRE4 uses the SC70-6 (DCK) package: 2.0 mm × 1.25 mm × 0.9 mm (max height), with 0.65 mm lead pitch. It is RoHS-compliant, moisture-sensitive level 1 (unlimited floor life), and marked "CPF". This ultra-small outline package enables high-density routing in portable, wearable, and miniaturized industrial electronics.
