Device Overview
Nexperia 74HC157D,653 is an exact-order quad 2-input multiplexer supplied in SOIC-16. For substitution or design review, the strongest comparison points are Device Function (quad 2-input multiplexer), Supply Voltage (2.0 to 6.0 V), Channel Count (4).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Device Function | quad 2-input multiplexer | 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. |
| Channel Count | 4 | Defines the number or arrangement of parallel signal/control paths and therefore the resources a replacement must provide. |
| Exact Package | SOIC-16 | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
| Data Path | non-inverting | Defines functional logic or signal-routing behavior; a substitute must preserve the required truth table, direction and control-state behavior. |
| Enable Behavior | HIGH enable forces outputs LOW | Defines functional logic or signal-routing behavior; a substitute must preserve the required truth table, direction and control-state behavior. |
Logic and Interface Selection Notes
At quad 2-input multiplexer, the device function defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. Channel Count is 4. Defines the number or arrangement of parallel signal/control paths and therefore the resources a replacement must provide. At non-inverting, the data path defines functional logic or signal-routing behavior; a substitute must preserve the required truth table, direction and control-state behavior. At HIGH enable forces outputs LOW, the enable behavior defines functional logic or signal-routing behavior; a substitute must preserve the required truth table, direction and control-state behavior.
2.0 to 6.0 V is the stated supply voltage value. Defines compatibility with the available board power rail and required bias range.
At SOIC-16, the exact package determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
