A 4-bit bidirectional bus transceiver, this HC/UH family logic IC features true output polarity and independent control. Operating across a wide temperature range from -55°C to 125°C, it supports supply voltages from 2V to 6V with a nominal 4.5V. The device is housed in a 14-terminal PDSO package with a JEDEC code of R-PDSO-G14, measuring 3.9mm in width and 8.65mm in length. Key performance metrics include a propagation delay of 220ns, with a typical 27ns at nominal supply voltage, and a load capacitance of 150pF.
