onsemi Signal Switches, Multiplexers, Decoders 74ACT158MTC

The 74ACT158MTC is a high-speed quad 2-input multiplexer designed to select four bits of data from two sources using common Select and Enable inputs. The outputs are buffered and present the selected data in inverted form. The Enable input is active-LOW, which means when it is HIGH, all outputs are forced HIGH regardless of other inputs. This device can function as a 4-pole, 2-position switch, making it suitable for applications such as moving data from two groups of registers to four common output buses or as a function generator for implementing gating functions. The 74ACT158MTC operates with a supply voltage range of 4.5V to 5.5V and is rated for an operating temperature range of -40¬8C to +85¬8C. It features TTL-compatible inputs and can source or sink up to 24 mA at the outputs. The device is available in a 16-lead Thin Shrink Small Outline Package (TSSOP), which is compact and suitable for space-constrained applications.
