Nexperia USA Inc. 74LVC3G16DPH

Overview

74LVC3G16DPH from Nexperia is a triple non-inverting buffer IC designed for level translation between 3.3 V and 5 V logic domains, featuring 1.65 V to 5.5 V supply operation, ±24 mA output drive at 3.0 V, IOFF partial power-down protection, and operation across –40 °C to +125 °C. It enables robust signal integrity in mixed-voltage I/O interfacing on compact PCBs.

For engineers reviewing the 74LVC3G16DPH datasheet, 74LVC3G16DPH pinout, 74LVC3G16DPH application, or 74LVC3G16DPH equivalent, this device is selected for voltage-level bridging in FPGA I/O expansion, microcontroller peripheral buffering, and industrial control bus conditioning where low-power CMOS compatibility and 5 V tolerance are mandatory.

Technical Context

This device implements three independent CMOS buffer stages with identical input/output characteristics. Each channel supports bidirectional voltage translation via 5 V-tolerant inputs and outputs, enabling interoperability between legacy 5 V TTL and modern 3.3 V LVC logic without external resistors or level-shifting circuitry.

The IOFF circuit actively disables all outputs when VCC = 0 V, limiting backflow current to ≤±10 μA (at 5.5 V applied), satisfying JEDEC JESD78 latch-up immunity (>250 mA) and HBM ESD robustness (>2000 V). Propagation delay is specified down to 0.5 ns (typ.) at 5.5 V supply.

FAQ

Can 74LVC3G16DPH operate with VCC = 1.8 V while driving 5 V inputs?

Yes. At VCC = 1.8 V, the device accepts 5 V-tolerant inputs (VI up to 6.5 V) and produces valid CMOS outputs referenced to 1.8 V. Input thresholds (VIH = 1.2 V min, VIL = 0.6 V max) ensure reliable detection of 3.3 V or 5 V logic levels, making it ideal for down-translation scenarios.

What is the maximum capacitive load the outputs can drive without exceeding timing specs?

The datasheet specifies dynamic characteristics with CL = 30–50 pF. At VCC = 3.3 V and CL = 50 pF, tPD remains within 5.1 ns (max). Driving >50 pF increases propagation delay nonlinearly and may cause overshoot; for >100 pF loads, series termination or buffer staging is recommended.

Does IOFF protection activate automatically when VCC drops below a threshold?

Yes. The IOFF circuit engages when VCC falls near 0 V (tested at VCC = 0 V), disabling all outputs regardless of input state. Output leakage remains ≤±10 μA even with 5.5 V applied to any I/O pin-no external enable/disable control is needed.

Is the 74LVC3G16DPH pin-compatible with older 74LVC3G16 variants in TSSOP8?

Yes. All 74LVC3G16 devices in SOT505-2 (TSSOP8) share identical pinout, marking location (pin 1 indicator below "YU"), and mechanical dimensions. The "DPH" suffix denotes tape-and-reel packaging per EIA-481; electrical and thermal specs match Rev. 5 documentation.
