Device Overview
74AVCH4T245BQ,115 is a 4-bit dual-supply level-translating transceiver in DHVQFN-16. VCC(A) and VCC(B) are independently supplied from 0.8 to 3.6 V, allowing bidirectional translation between common low-voltage logic nodes.
Confirmed Technical and Ordering Data
| Parameter | Confirmed value | Scope / condition |
|---|---|---|
| Logic Function | 4-bit dual-supply translating transceiver | bidirectional; configurable as two 2-bit or one 4-bit path |
| Supply A | 0.8 to 3.6 V | VCC(A) |
| Supply B | 0.8 to 3.6 V | VCC(B) |
| Direction Control | nDIR | HIGH A-to-B; LOW B-to-A |
| Output Enable | nOE | disables outputs into high impedance |
| Maximum Data Rate | 380 Mbit/s | for translation with supply nodes at or above 1.8 V to 3.3 V per datasheet headline |
| Partial Power-Down | IOFF plus suspend behavior | high-impedance outputs when a supply is at GND |
| Bus Hold | Active bus hold on powered-side data inputs | reduces need for external pull resistors on floating inputs |
| Temperature Range | -40 to +125 °C | BQ package ordering table |
| Exact Package | DHVQFN16, SOT763-1 | 16 terminals; 2.5 x 3.5 x 0.85 mm |
Engineering Selection Guidance
The 380 Mbit/s headline is conditional on the translation voltage range; lower-voltage translations have lower datasheet headline rates, so 380 Mbit/s must not be treated as universal across 0.8 to 3.6 V operation.
nDIR defines transfer direction and nOE can place the outputs in high impedance, which matters for bus ownership during voltage-domain handoff.
When either supply is at ground, the partial-power-down/suspend behavior drives the affected I/O into high impedance; this is different from normal enabled translation.
