Nexperia USA Inc. 74AHC1G125GM,132

Overview

74AHC1G125GM,132 from Nexperia is a single CMOS bus buffer/line driver with 3-state output, overvoltage-tolerant inputs (up to 5.5 V), operating from 2.0 V to 5.5 V supply, specified for -40 °C to +125 °C, and housed in a 6-terminal XSON6 (SOT886) package. It functions as a level-translating unidirectional buffer in mixed-voltage digital interfaces.

For engineers reviewing the 74AHC1G125GM,132 datasheet, 74AHC1G125GM,132 pinout, 74AHC1G125GM,132 application, or 74AHC1G125GM,132 equivalent, key selection criteria include its 3-state control timing (t_en/t_dis ≤ 9.5 ns at 5 V), input overvoltage tolerance, rail-to-rail output swing, and compact 1.0 × 1.45 mm XSON6 footprint for space-constrained PCBs.

Technical Context

This device implements a single non-inverting buffer with active-low 3-state enable (OE), where output Y follows input A when OE is LOW and enters high-impedance state when OE is HIGH. Its CMOS input threshold (VIH = 3.85 V, VIL = 1.65 V at VCC = 5.5 V) ensures compatibility with standard 5 V logic while accepting up to 5.5 V inputs regardless of supply voltage.

Propagation delay (tpd ≤ 7.0 ns at VCC = 5.5 V, CL = 15 pF), symmetrical output drive (|IOH| = |IOL| = 8 mA), and low ICC (≤ 40 μA at VCC = 5.5 V) support high-speed, low-power signal routing in microcontroller peripheral buses, sensor interface lines, and FPGA I/O expansion paths.

FAQ

What is the maximum input voltage the 74AHC1G125GM,132 can tolerate?

The 74AHC1G125GM,132 accepts input voltages up to 5.5 V on both A and OE pins, independent of VCC level (2.0–5.5 V). This overvoltage tolerance is guaranteed per datasheet Section 8 (Limiting Values) and enables safe interfacing with 5 V signals even when powered from 3.3 V or 2.5 V supplies.

Does the n.c. pin on the XSON6 package require grounding or leaving floating?

Pin 5 (n.c.) in the SOT886 package is internally unconnected and must remain unconnected on the PCB. Nexperia's datasheet Section 6.2 explicitly defines it as "not connected"; grounding or routing it risks unintended coupling or violates package thermal design rules. No external connection is permitted or required.

How does the 74AHC1G125GM,132 behave when VCC is 0 V but inputs are driven?

When VCC = 0 V, the device enters power-down mode: ICC drops to ≤1.0 μA (Section 10), and inputs A/OE exhibit ≤0.1 μA leakage (II). Outputs remain high-impedance regardless of OE state. This behavior enables hot-swap and partial-power-down use cases without latch-up risk, as confirmed by JESD78 Class II Level A latch-up testing (>100 mA).

Can the 74AHC1G125GM,132 drive a 50 pF load at 5 V with guaranteed timing?

Yes - at VCC = 4.5–5.5 V and CL = 50 pF, the datasheet guarantees tpd ≤ 7.5 ns, ten ≤ 9.5 ns, and tdis ≤ 11.0 ns across -40 °C to +125 °C (Section 11, Table 8). These values include worst-case process/voltage/temperature corners, ensuring timing closure in production systems without derating.
