Frequently Asked Questions
What is the operating voltage and logic family of the SN74AHCT245PW?
The SN74AHCT245PW operates at 5V VCC and belongs to the AHCT/VHCT/VT logic family. It features TTL-compatible inputs, making it suitable for interfacing 3.3V logic with 5V bus systems without additional level-shifting components.
How does the direction control work on the SN74AHCT245PW?
The SN74AHCT245PW uses a COMMON CONTROL bidirectional configuration with a DIR pin that selects data flow direction and an active-low OE pin that enables or disables the outputs. When DIR is HIGH, data flows from A to B; when LOW, data flows from B to A across all 8 bits simultaneously.
What package does the SN74AHCT245PW come in and what are its key electrical parameters?
The SN74AHCT245PW is housed in a 20-pin TSSOP (JESD-30 code R-PDSO-G20) package. Key electrical parameters include a maximum output low current (I_OL) of 8mA, a load capacitance (CL) of 50pF, and compliance with JESD-609 code e4 for lead-free (RoHS) packaging.
What are typical applications for the SN74AHCT245PW?
Typical applications include data bus buffering between microcontrollers and memory devices, bidirectional level translation between 3.3V and 5V logic, backplane signal driving in industrial control boards, and peripheral interface buffering in embedded systems and communication equipment.
Is the SN74AHCT245PW in stock and where can I purchase it?
Yes, the SN74AHCT245PW is available in stock from multiple distributors worldwide starting from approximately $0.34 per unit. Volume pricing is available for bulk orders, and worldwide shipping is supported through authorized Texas Instruments distribution channels.
