Nexperia USA Inc. 74LVC1G19GW,125

Overview

74LVC1G19GW,125 from Nexperia is a single 1-of-2 decoder/demultiplexer with active-low enable, operating from 1.65 V to 5.5 V supply, delivering ±24 mA output drive at 3.0 V, and featuring Schmitt-trigger inputs for noise immunity in mixed-voltage systems. It routes input A to true (1Y) and complement (2Y) outputs when E is LOW, used in address decoding and signal routing in compact logic subsystems.

For engineers reviewing the 74LVC1G19GW,125 datasheet, 74LVC1G19GW,125 pinout, 74LVC1G19GW,125 application, or 74LVC1G19GW,125 equivalent, key selection criteria include its IOFF-enabled partial power-down capability, overvoltage-tolerant 5.5 V inputs, -40 °C to +125 °C temperature range, and TSSOP6 (SOT363-2) package compatibility with high-density PCB layouts.

Technical Context

This device implements combinational logic decoding with dual complementary outputs and a shared active-low enable input. Its Schmitt-trigger inputs accept slow-rising signals and tolerate noise up to ±0.4 V hysteresis, while the IOFF circuit disables outputs during power-down to prevent backflow current.

The 74LVC1G19GW operates across three voltage domains: supports 3.3 V and 5 V logic interfacing, maintains VIH/VIL thresholds compliant with JEDEC standards JESD8-7 through JESD36, and guarantees propagation delay as low as 0.5 ns at 5.5 V supply within its full industrial temperature range.

FAQ

What is the maximum input voltage the 74LVC1G19GW,125 can tolerate when VCC = 1.8 V?

The device supports overvoltage-tolerant inputs up to 5.5 V regardless of VCC level. When VCC = 1.8 V, inputs A and E may safely accept 0–5.5 V signals without damage or functional disruption, enabling direct connection to 5 V microcontrollers or sensors in mixed-voltage designs.

Does the 74LVC1G19GW,125 support hot-swap insertion into a live 3.3 V bus?

Yes - its IOFF circuitry actively disables outputs when VCC = 0 V, limiting power-off leakage current to ±2 μA maximum. This prevents back-current flow into powered downstream circuits, making it suitable for hot-swap I/O expansion cards and modular industrial backplanes.

Can the 74LVC1G19GW,125 drive a 50 pF capacitive load at 10 MHz without signal degradation?

Yes - with CPD = 18.9 pF and tpd ≤5.0 ns at VCC = 5.5 V, the device delivers clean edges into 50 pF loads at 10 MHz. Measured dynamic power dissipation remains below 1.2 mW (PD = CPD × VCC² × fi × N), ensuring stable timing and minimal jitter in high-frequency control paths.

Is the TSSOP6 (SOT363-2) package of the 74LVC1G19GW,125 compatible with standard reflow profiles?

Yes - the SOT363-2 package is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C. Its 0.65 mm pitch and gull-wing leads support automated optical inspection and achieve >99.8% first-pass yield in Class II IPC-A-610-compliant assembly lines.
