Texas Instruments SN74LVC1G58DCKRG4

Overview

SN74LVC1G58DCKRG4 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). It operates from 1.65 V to 5.5 V, delivers ±24-mA drive at 3.3 V, features Schmitt-trigger inputs with hysteresis (ΔVT = 0.53–1.11 V), and achieves 6.3 ns max propagation delay at 3.3 V. It enables compact signal conditioning in space-constrained sensor interface and power management circuits.

For engineers reviewing the SN74LVC1G58DCKRG4 datasheet, SN74LVC1G58DCKRG4 pinout, SN74LVC1G58DCKRG4 application, or SN74LVC1G58DCKRG4 equivalent, key selection criteria include its 3-input configurability, Ioff support for live insertion, 1.65–5.5-V voltage translation capability, Schmitt-trigger noise immunity, and SC70-6 package footprint compatibility with high-density PCB layouts.

Technical Context

The SN74LVC1G58DCKRG4 implements a 3-bit function-select architecture where In0–In2 determine output logic state per an 8-row truth table. Its Schmitt-trigger inputs provide distinct VT+ (1.5–3.33 V) and VT– (0.35–2.29 V) thresholds, enabling robust noise rejection in slow-rising or noisy environments.

It integrates Ioff circuitry that disables outputs during partial power-down, preventing back-drive current when VCC = 0 V. All inputs tolerate up to 5.5 V regardless of VCC, supporting mixed-voltage interfacing without level shifters.

FAQ

What logic functions does the SN74LVC1G58DCKRG4 support?

The SN74LVC1G58DCKRG4 supports eight logic configurations determined by its three input pins (In0–In2): AND, OR, NAND, NOR, XOR, inverter, and noninverter. Each combination maps directly to a row in its truth table, enabling hardware-programmable logic without firmware involvement. This makes SN74LVC1G58DCKRG4 ideal for fixed-function digital conditioning where reprogrammability isn't needed but flexibility across variants is valuable.

Does the SN74LVC1G58DCKRG4 support mixed-voltage interfacing?

Yes, the SN74LVC1G58DCKRG4 supports true mixed-voltage operation: inputs accept voltages up to 5.5 V regardless of VCC level (1.65–5.5 V), and outputs swing rail-to-rail. For example, it can translate a 5-V enable signal to a 1.8-V microcontroller GPIO while powered from 1.8 V - no external level shifter required. This capability is explicitly specified in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the SN74LVC1G58DCKRG4 datasheet.

What is the purpose of the Ioff feature in the SN74LVC1G58DCKRG4?

The Ioff feature in the SN74LVC1G58DCKRG4 disables output drivers when VCC = 0 V, limiting off-state leakage to ±10 µA. This prevents current backflow from live system buses into a powered-down section - critical for hot-plug cards, modular power supplies, or systems with staggered power sequencing. The SN74LVC1G58DCKRG4's Ioff behavior is guaranteed across –40°C to +125°C and is integral to its JESD78 latch-up compliance.

How does the Schmitt-trigger input improve noise immunity in the SN74LVC1G58DCKRG4?

The SN74LVC1G58DCKRG4's Schmitt-trigger inputs feature asymmetric thresholds: VT+ (1.5–3.33 V) for rising edges and VT– (0.35–2.29 V) for falling edges, yielding hysteresis (ΔVT) of 0.53–1.11 V. This gap rejects noise spikes smaller than ΔVT, preventing false toggling on slow or noisy signals - such as those from mechanical switches or resistive sensors. Unlike standard CMOS inputs, SN74LVC1G58DCKRG4 requires no external RC network to achieve reliable edge detection.

Is the SN74LVC1G58DCKRG4 pin-compatible with other SC70-6 logic gates?

SN74LVC1G58DCKRG4 uses the standard SC70-6 (DCK) pinout: Pin 1 = In0, Pin 2 = In1, Pin 3 = GND, Pin 4 = In2, Pin 5 = VCC, Pin 6 = Y. This matches TI's SN74LVC1Gxx series in DCK packaging (e.g., SN74LVC1G00, SN74LVC1G08), enabling layout reuse across logic families. However, function differs - SN74LVC1G58DCKRG4 is configurable, while others implement fixed gates - so schematic substitution requires logic verification.
