Diodes Incorporated 74AHC1G04W5-7

Overview

74AHC1G04W5-7 from Diodes Incorporated is a single CMOS inverter gate in SOT25 package, operating from 2.0V to 5.5V supply, delivering ±8 mA output drive at 5.0V, with Schmitt-trigger input for noise immunity and 4.3 ns typical propagation delay (CL=15pF, VCC=3.3V). It serves as a level-shifting or signal-conditioning element in low-power digital logic interfaces.

For engineers reviewing the 74AHC1G04W5-7 datasheet, 74AHC1G04W5-7 pinout, 74AHC1G04W5-7 application, or 74AHC1G04W5-7 equivalent, key selection criteria include supply voltage flexibility, input hysteresis tolerance, output drive capability at 3.3V/5V, and thermal resistance (θJA = 195°C/W) in space-constrained PCB layouts.

Technical Context

This device implements a single positive-logic inverter function (Y = A̅) using advanced AHC CMOS process technology. Its Schmitt-trigger input provides 0.36V–0.55V hysteresis (VCC = 3V–5.5V), enabling robust operation with slow-rising or noisy input signals.

It supports dual-voltage system interfacing across 2.0V–5.5V rails, with rail-to-rail output swing and guaranteed switching performance down to -40°C. Input clamp current (±20 mA) and latch-up immunity (>100 mA per JESD78 Class II) ensure resilience in transient-prone environments.

FAQ

Is the NC pin (Pin 1) required to be tied to ground or left floating?

Pin 1 is internally unconnected and must remain floating per Diodes Incorporated design. Grounding it offers no benefit and may risk unintended coupling in high-density layouts. The datasheet explicitly defines it as "No Connection" with no functional or thermal requirement for termination.

Can the 74AHC1G04W5-7 drive a 50 pF capacitive load at 10 MHz without signal degradation?

Yes - with tpd = 6.1 ns (typ.) at CL = 50 pF and VCC = 3.3V, the device maintains monotonic edges and full rail swing. Rise/fall times remain <3 ns, ensuring >30% margin against 10 MHz period (100 ns), provided PCB trace capacitance is included in the 50 pF budget.

Does the Schmitt-trigger input affect propagation delay symmetry between rising and falling edges?

No - the datasheet specifies identical tPLH and tPHL values (both reported as tpd), confirming symmetrical delay behavior. The hysteresis affects only input threshold levels (VT+ and VT−), not internal gate timing architecture, preserving predictable edge-to-edge timing in oscillators or clock dividers.

What is the maximum allowable continuous output current when sinking 8 mA at VCC = 5V?

The absolute maximum rating is ±25 mA continuous output current, but the DC electrical characteristics specify guaranteed performance only up to ±8 mA at VCC = 5V. Sustained 8 mA operation is fully characterized and safe; exceeding it risks VOL > 0.55V and thermal derating beyond 125°C ambient.
