Nexperia USA Inc. 74LVC1G97GV,125

Overview

74LVC1G97GV,125 from Nexperia is a single-channel, low-power configurable multiple-function logic gate with Schmitt-trigger inputs, supporting MUX, AND, OR, NAND, NOR, inverter, and buffer configurations via three input pins (A, B, C). It operates from 1.65 V to 5.5 V, tolerates 5 V inputs while powered at 3.3 V, and features IOFF partial power-down protection. It is used in voltage-level translation and reconfigurable logic routing in space-constrained industrial control interfaces.

For engineers reviewing the 74LVC1G97GV,125 datasheet, 74LVC1G97GV,125 pinout, 74LVC1G97GV,125 application, or 74LVC1G97GV,125 equivalent, this device serves as a compact, rail-to-rail compatible logic configurator for mixed-voltage signal conditioning, I/O buffering, and function selection in portable instrumentation and programmable logic subsystems.

Technical Context

The 74LVC1G97GV,125 implements a single configurable logic cell using CMOS technology with Schmitt-trigger inputs for enhanced noise immunity and hysteresis (VH = 0.50 V typical at VCC = 3.0 V). Its 3-bit configuration (A/B/C) selects one of seven standard logic functions without external components.

It supports true bidirectional voltage translation: inputs accept 0–5.5 V regardless of VCC (1.65–5.5 V), enabling interoperability between 3.3 V and 5 V domains. The IOFF circuit disables outputs during power-down, blocking backflow current when VCC = 0 V - critical for hot-swap and partial-power systems.

FAQ

Can 74LVC1G97GV,125 be used as a level shifter between 1.8 V and 5 V domains?

Yes - its inputs tolerate 0–5.5 V regardless of VCC, and outputs swing rail-to-rail. When VCC = 1.8 V, it accepts 5 V inputs safely and outputs 0/1.8 V logic; when VCC = 5 V, it drives 0/5 V outputs while accepting 1.8 V inputs. No external biasing or resistors are needed, and propagation delay remains under 14.4 ns at 1.8 V.

What is the minimum input rise/fall time supported with Schmitt-trigger operation?

The device does not specify a minimum edge rate, but Schmitt-trigger hysteresis (0.50 V typ. at 3.0 V) ensures reliable switching for input edges slower than 10 μs. For edges faster than 2 ns, standard CMOS timing applies. Input capacitance is 2.5 pF, limiting practical minimum rise time to ~100 ps into 50 Ω due to RC constraints.

How is the logic function selected - by external wiring or internal register?

Function selection is hardwired via the DC states of inputs A, B, and C - no clock, register, or programming interface is involved. Each unique 3-bit combination (e.g., A=H, B=L, C=H) maps directly to a specific logic function (e.g., NAND) per Table 4. Strapping pins to VCC/GND fixes the function permanently in unattended systems.

Does 74LVC1G97GV,125 support hot insertion when VCC is off?

Yes - the IOFF circuit actively disables the output and limits leakage to ±2 μA when VCC = 0 V, preventing backdrive current from live buses (e.g., 5 V I²C or UART lines) into the unpowered device. This meets JEDEC JESD78 Class II latch-up immunity and protects both the IC and upstream drivers during hot-plug events.
