The SN74ABT16646 is a 16-bit bus transceiver and register designed by Texas Instruments. It is part of the Widebus™ family and utilizes an EPIC-IIB™ BiCMOS design for reduced power dissipation. This device can function as two 8-bit transceivers or one 16-bit transceiver, with data clocked into registers on the low-to-high transition of the clock inputs.
Key electrical characteristics include TTL input and output types, with high drive outputs capable of -32 mA IOH and 64 mA IOL. The device operates over a temperature range of -40°C to 85°C. Features such as over-voltage tolerant inputs, partial power down (Ioff), and very high speed (tpd 5-10ns) are included.
Available in TSSOP (DGG) and SSOP (DL) packages, as well as a fine-pitch ceramic flat package (WD), the SN74ABT16646 is designed for optimized PCB layout with a flow-through architecture. Latch-up performance exceeds 500 mA per JESD 17, and typical output ground bounce is less than 1 V at VCC = 5 V, TA = 25°C. Distributed VCC and GND pin configurations minimize high-speed switching noise.
The operating temperature range is -40°C to 85°C.
The device is available in TSSOP, SSOP, and Ceramic Flat packages, all surface-mount.
It has 16 channels.
The maximum output current high is -32 mA and output current low is 64 mA.
It belongs to the ABT (Advanced BiCMOS Technology) family.
Yes, it features over-voltage tolerant inputs.
Typical output ground bounce is less than 1 V at VCC = 5 V, TA = 25°C.
