Device Overview
Nexperia 74HC237D,653 is an exact-order 3-to-8 line decoder/demultiplexer with address latches supplied in SOIC-16. The main engineering checks for this variant are Device Function (3-to-8 line decoder/demultiplexer with address latches), Supply Voltage (2.0 to 6.0 V), Output Count (8).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Device Function | 3-to-8 line decoder/demultiplexer with address latches | 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 (74HC family operating range) | Defines compatibility with the available board power rail and required bias range. |
| Output Count | 8 | Defines how many decoded or controlled output lines are available from one device. |
| Address Inputs | 3 | Defines the number of address/control bits used to select an output or internal state. |
| Address Latch | 3-bit address latches | Defines whether address state can be captured and held independently of later input changes. |
| Exact Package | SOIC-16 | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
Logic and Interface Selection Notes
At 3-to-8 line decoder/demultiplexer with address latches, the device function defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared.
At 2.0 to 6.0 V, the supply voltage defines compatibility with the available board power rail and required bias range. Technical condition: 74HC family operating range.
Exact Package is SOIC-16. Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
8 is the stated output count value. Defines how many decoded or controlled output lines are available from one device. At 3, the address inputs defines the number of address/control bits used to select an output or internal state.
For address latch, 3-bit address latches is the approved value. Defines whether address state can be captured and held independently of later input changes.
