Device Overview
74HC151D,653 is a Nexperia 8-input multiplexer with complementary outputs in a SOIC-16 package. The main engineering checks for this variant are Device Function (8-input multiplexer with complementary outputs), Supply Voltage (2.0 to 6.0 V), Input Count (8).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Device Function | 8-input multiplexer with complementary outputs | Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. |
| Supply Voltage | 2.0 to 6.0 V | Defines compatibility with the available board power rail and required bias range. |
| Input Count | 8 | Defines how many source signals the multiplexer/logic function can accept and therefore whether one device covers the required fan-in. |
| Select Inputs | 3 | Defines how many control/address lines are required to choose among the available input paths. |
| Enable | active-low enable | Defines functional logic or signal-routing behavior; a substitute must preserve the required truth table, direction and control-state behavior. |
| Exact Package | SOIC-16 | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
Logic and Interface Selection Notes
For device function, 8-input multiplexer with complementary outputs is the approved value. Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. At active-low enable, the enable defines functional logic or signal-routing behavior; a substitute must preserve the required truth table, direction and control-state behavior.
For supply voltage, 2.0 to 6.0 V is the approved value. Defines compatibility with the available board power rail and required bias range.
SOIC-16 is the stated exact package value. Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
For input count, 8 is the approved value. Defines how many source signals the multiplexer/logic function can accept and therefore whether one device covers the required fan-in. 3 is the stated select inputs value. Defines how many control/address lines are required to choose among the available input paths.
