Device Overview
Nexperia 74HC4094PW,118 is an exact-order 8-stage shift-and-store bus register supplied in TSSOP-16. The main engineering checks for this variant are Device Function (8-stage shift-and-store bus register), Supply Voltage (2.0 to 6.0 V), Bit Count (8).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Device Function | 8-stage shift-and-store bus register | 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. |
| Bit Count | 8 | Defines the parallel state/register width and therefore how many bits can be stored, shifted or controlled per device. |
| Maximum Frequency | 95 MHz (74HC4094 D/PW parametric) | Defines the operating frequency or RF band that must cover the intended signal frequencies. |
| Output Drive | ±5.2 mA (parametric class) | Defines output drive strength and therefore the external load, fanout or pull-up/down burden the pin can support. |
| Exact Package | TSSOP-16 | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
Logic and Interface Selection Notes
Device Function is 8-stage shift-and-store bus register. Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared.
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. 95 MHz is the stated maximum frequency value. Defines the operating frequency or RF band that must cover the intended signal frequencies. Technical condition: 74HC4094 D/PW parametric.
At TSSOP-16, the exact package determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
Bit Count is 8. Defines the parallel state/register width and therefore how many bits can be stored, shifted or controlled per device. At +/-5.2 mA, the output drive defines output drive strength and therefore the external load, fanout or pull-up/down burden the pin can support. Technical condition: parametric class.
When choosing a 16-pin 74HC4094 assembly format, compare 74HC4094D,653 (SOIC/SO16, SOT109-1) with this 74HC4094PW,118 (TSSOP16, SOT403-1). Nexperia lists both as 8-bit shift-and-store registers, but the two mechanical footprints are different; neither package should be assumed to fit the other’s PCB pads.
