Logic device/transceiver/encoder

MC74HC153 has the same pinout as LS153. The device inputs are compatible with standard CMOS outputs; pull-up resistors are included for compatibility with LSTTL outputs. The address input selects one of the four data inputs to each multiplexer. Each multiplexer has an active-low polarity control and non-inverting output. The HC153 is functionally similar to the HC253, with 3-state outputs.

The NLSV8T244 is an 8-bit configurable dual-supply voltage level translator. The input An and output Bn ports are designed to track two different supply rails, VCCA and VCCB, respectively. Both supply rails are configurable from 0.9 V to 4.5 V, allowing universal low-voltage conversion from the input An to output Bn ports.
