This document is the user manual of the SN74LVC16646 16-bit bus transceiver and register
The SN74LVC16646 is a member of the Widebus™ Family featuring EPIC™ submicron process technology. It functions as two 8-bit transceivers or one 16-bit transceiver, utilizing D-type flip-flops and control circuitry for multiplexed data transmission between buses A and B.
The device includes active bus-hold circuitry to eliminate the need for external pull-up or pull-down resistors. It supports real-time transfer of stored data and isolation modes, with operation characterized from -40°C to 85°C.
| Supply Voltage Range | 2.7 V to 3.6 V |
|---|---|
| Operating Temperature Range | -40°C to 85°C |
| Package Options | Plastic 300-mil Shrink Small-Outline (DL) and Thin Shrink Small-Outline (DGG) |
| Output Ground Bounce | < 0.8 V at Voc = 3.3 V, Ta = 25°C |
The recommended operating conditions specify a supply voltage (Voc) between 2.7 V and 3.6 V.
No, the active bus-hold circuitry eliminates the need for external pullup/pulldown resistors.
The device is available in Plastic 300-mil Shrink Small-Outline (DL) and Thin Shrink Small-Outline (DGG) packages.
