Device Overview
Nexperia 74AVC4T774GUX is an exact-order 4-bit dual-supply bidirectional voltage-level translating transceiver with per-bit direction control and 3-state outputs supplied in XQFN-16. For substitution or design review, the strongest comparison points are Device Function, Vcca Range (0.8 to 3.6 V), Vccb Range (0.8 to 3.6 V).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Device Function | 4-bit dual-supply bidirectional voltage-level translating transceiver with per-bit direction control and 3-state outputs | Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. |
| Vcca Range | 0.8 to 3.6 V | Defines the allowed logic-domain supply range and therefore voltage-domain compatibility for level translation between the A-side and B-side rails. |
| Vccb Range | 0.8 to 3.6 V | Defines the allowed logic-domain supply range and therefore voltage-domain compatibility for level translation between the A-side and B-side rails. |
| Maximum Data Rate | 380 Mbit/s (>=1.8 V to 3.3 V translation) | Defines interface throughput and timing compatibility with the source and destination devices. |
| Output Drive | ±12 mA (parametric class) | Defines output drive strength and therefore the external load, fanout or pull-up/down burden the pin can support. |
| Exact Package | XQFN-16 | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
| Direction Control | independent DIR input per bit | Defines a selection-critical engineering characteristic that a compatible substitute must preserve under the stated conditions. |
Logic and Interface Selection Notes
Device Function is 4-bit dual-supply bidirectional voltage-level translating transceiver with per-bit direction control and 3-state outputs. Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared.
The exact package is XQFN-16; this determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
For vcca range, 0.8 to 3.6 V is the approved value. Defines the allowed logic-domain supply range and therefore voltage-domain compatibility for level translation between the A-side and B-side rails. 0.8 to 3.6 V is the stated vccb range value. Defines the allowed logic-domain supply range and therefore voltage-domain compatibility for level translation between the A-side and B-side rails.
At 380 Mbit/s, the maximum data rate defines interface throughput and timing compatibility with the source and destination devices. Technical condition: >=1.8 V to 3.3 V translation. The output drive is +/-12 mA; this defines output drive strength and therefore the external load, fanout or pull-up/down burden the pin can support. Technical condition: parametric class.
Direction Control is independent DIR input per bit. Defines a selection-critical engineering characteristic that a compatible substitute must preserve under the stated conditions.
