1 / 10 page 1 Standard Products UT54ACS253/UT54ACTS253 Dual 4-Input Multiplexers, Three-State Outputs Datasheet November 2010 www.aeroflex.com/logic FEATURES Permits multiplexing from N lines to 1 line Performs parallel-to-serial conversion 1.2μ CMOS - Latchup immune High speed Low power consumption Single 5 volt supply Available QML Q or V processes Flexible package - 16-pin DIP - 16-lead flatpack UT54ACS253 - SMD 5962-96574 UT54ACTS253 - SMD 5962-96575 DESCRIPTION The UT54ACS253 and the UT54ACTS253 are 1-line to 4-line multiplexers that contain drivers to supply full binary decoding. Separate output control inputs are provided for each of the two four-line sections. Use the three-state outputs to drive data lines in bus-organized systems. With all but one of the common outputs disabled the low-impedance of the single enable output will drive the bus line to a high or low logic level. Each output has its own strobe (G). The devices are characterized over full military temperature range of -55 °C to +125°C.
