Frequently Asked Questions
What is the function of the SN74AHCT157PWRG4?
The SN74AHCT157PWRG4 is a quad 2-to-1 data multiplexer that selects between two sets of four input signals and routes them to four outputs based on a single common select input. This allows one of two data buses to be passed through to the output, enabling flexible data routing in digital designs.
What logic family does the SN74AHCT157PWRG4 belong to?
The SN74AHCT157PWRG4 belongs to the AHCT (Advanced High-speed CMOS with TTL-compatible inputs) logic family. This family accepts TTL-level inputs (VIH of 2V) while providing full CMOS output swing, making it ideal for interfacing between TTL and CMOS logic systems.
What is the output sink current of the SN74AHCT157PWRG4?
The SN74AHCT157PWRG4 provides a maximum output sink current (IOL) of 8 mA per output pin. This is sufficient to drive standard TTL and CMOS logic loads directly, as well as low-current LEDs in simple indicator applications without external buffers.
What package does the SN74AHCT157PWRG4 use?
The SN74AHCT157PWRG4 is housed in a 16-pin TSSOP (Thin Shrink Small Outline Package), designated PDSO-G16. The TSSOP package has a fine 0.65 mm pin pitch that minimizes board area while remaining accessible for standard SMT assembly processes.
What is the load capacitance specification for the SN74AHCT157PWRG4?
The SN74AHCT157PWRG4 is specified with a load capacitance (CL) of 50 pF. This capacitive load value is used as the standard test condition for timing specifications such as propagation delay, and reflects typical PCB trace and input capacitance seen in real designs.
