Texas Instruments Standard Linear and Logic Signal Switches, Multiplexers, Decoders SN74HC257DR

The SN74HC257DR is a 4-channel multiplexer designed for high-performance signal switching applications. It operates within a wide voltage range of 2 V to 6 V and features high-current inverting outputs capable of driving up to 15 LSTTL loads. The device has a low power consumption of 80 ¬µA maximum ICC and a typical propagation delay (tpd) of 9 ns, making it suitable for fast switching applications. This multiplexer provides bus interface capabilities from multiple sources, ensuring that the 3-state outputs do not load the data lines when the output-enable (G) input is high. The device is available in a TSSOP package, which is suitable for space-constrained designs. The operating temperature range is from -40¬8C to 85¬8C, allowing for use in various environmental conditions. Engineers considering the SN74HC257DR for their projects will find it beneficial for applications requiring efficient signal multiplexing with low power requirements and fast response times.
