Nexperia USA Inc. 74LVC1G34GN,132

Overview

74LVC1G34GN,132 from Nexperia is a single non-inverting buffer with 3.3 V supply operation, ±24 mA output drive, 3.7 ns typical propagation delay at V_CC = 3.3 V, and 5 V tolerant inputs. It serves as a level-shifting logic driver in low-power digital interface circuits such as I²C bus buffering and GPIO signal conditioning.

For engineers reviewing the 74LVC1G34GN,132 datasheet, 74LVC1G34GN,132 pinout, 74LVC1G34GN,132 application, or 74LVC1G34GN,132 equivalent, key selection criteria include input voltage tolerance, output drive strength, propagation delay consistency across V_CC, and compatibility with 1.65–5.5 V supply rails in mixed-voltage systems.

Technical Context

This device implements a CMOS-based single-channel buffer with Schmitt-trigger input disabled and push-pull output stage. Its 5 V tolerant inputs enable direct interfacing with legacy 5 V logic while operating from a 3.3 V supply, eliminating external level shifters in mixed-voltage domains.

The LVC family architecture ensures rail-to-rail output swing, low dynamic power consumption (< 10 µA ICC at standby), and guaranteed monotonic switching behavior over temperature (−40 °C to +125 °C) and supply voltage variation.

FAQ

Is the 74LVC1G34GN,132 pin-compatible with other 74LVC1Gxx devices in XSON-6?

No. The 74LVC1G34GN,132 uses a dedicated 6-pin XSON layout with pins 1 (A), 2 (GND), 3 (Y), 4 (V_CC), and two N/C terminals (pins 5 and 6). Other 74LVC1Gxx variants like inverters or Schmitt triggers use different pin assignments and cannot be substituted without PCB revision.

Can this buffer drive a 50 Ω transmission line directly?

Yes. With ±24 mA output drive at V_CC = 3.3 V and rail-to-rail swing, it can source/sink sufficient current to terminate a 50 Ω line driven at ≤ 10 MHz. For higher frequencies, controlled-impedance routing and series termination remain recommended to suppress reflections.

What is the maximum capacitive load this device can drive while maintaining t_PD < 5 ns?

At V_CC = 3.3 V, the device maintains t_PD ≤ 4.8 ns up to C_L = 75 pF per the Nexperia datasheet (Rev. 5, Table 7). Beyond that, propagation delay increases linearly-e.g., 6.1 ns at 100 pF-due to RC charging effects at the output node.

Does the 74LVC1G34GN,132 support hot-swap or live-insertion?

Yes. Its I_OFF leakage ≤ 0.5 µA at V_CC = 0 V and 5 V tolerant inputs allow safe insertion into powered-backplane systems. However, V_CC must be ramped before applying input signals to avoid latch-up risk during power sequencing.
