OCTAL, HEX, AND QUAD D-TYPE FLIP-FLOPS WITH ENABLE
SN74LS257AN is a 16-pin dual 4-line to 1-line multiplexer/demultiplexer with address logic. It is manufactured by Texas Instruments (TI). Description: The SN74LS257AN is a dual 4-line to 1-line multiplexer/demultiplexer with address logic. It has two independent 4-line to 1-line multiplexers/demultiplexers with address logic. Each multiplexer/demultiplexer has four data inputs (A0A3), four data outputs (Y0Y3), an address input (G), an enable input (E), and an active low output enable (OE). Features: Low power consumption High speed operation High noise immunity High output drive capability TTL-compatible inputs High-impedance outputs in the high-impedance state Applications: The SN74LS257AN is commonly used in data and address multiplexing, memory decoding, and data routing applications. It can also be used in logic circuits, such as decoders, encoders, and multiplexers.
