Frequently Asked Questions
What is the SN74ABT646PW and what does it do?
The SN74ABT646PW is an octal (8-bit) bus transceiver with 3-state outputs from Texas Instruments' ABT logic family. It enables bidirectional data transfer between two buses using a direction control pin (DIR) and an output enable pin (OE), supporting non-inverting signal transmission at high speed.
What voltage levels does the SN74ABT646PW support?
The SN74ABT646PW operates with a supply voltage (VCC) of 4.5V to 5.5V and is designed to interface with both 3.3V and 5V logic signals. Its ABT family design allows it to accept 3.3V-level inputs while being powered at 5V, making it ideal for mixed-voltage system designs.
What package does the SN74ABT646PW come in?
The SN74ABT646PW is housed in a 24-pin TSSOP (Thin Shrink Small Outline Package), which provides a compact footprint suitable for space-constrained PCB designs. The 'PW' suffix in the part number specifically denotes this TSSOP-24 package.
What are typical applications for the SN74ABT646PW?
Typical applications include microprocessor data bus buffering, memory interface expansion, and backplane bus management in industrial and computing systems. It is also commonly used for bidirectional level shifting between 3.3V and 5V logic domains and in multi-card bus architectures requiring signal isolation and direction control.
