The SN74CBT3384C is a high-speed TTL-compatible FET bus switch with low ON-state resistance (ron), allowing for minimal propagation delay
The SN74CBT3384C is a high‑speed TTL‑compatible FET bus switch organized as two 5‑bit switches that can also operate as a single 10‑bit switch. It features bidirectional data flow, low ON‑state resistance, and active undershoot‑protection circuitry that limits undershoot to –2 V.
The device is offered in multiple package types (DB, DBQ, DGV, DW, PW) with typical ON‑state resistance of 3.2 mΩ, supply voltage range 4 V‑5.5 V, and continuous current capability of up to 100 mA. It supports partial‑power‑down mode and includes extensive packaging and reliability information.
| Supply voltage range (VCC) | 4 V to 5.5 V |
|---|---|
| Low‑level input voltage (VIL) | 0.8 V |
The device operates from 4 V up to 5.5 V supply voltage.
It can be used as two 5‑bit bus switches or as one 10‑bit bus switch.
