s identical in pinout to the LS153. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The Address Inputs select one of four Data Inputs from each multiplexer. Each multiplexer has an active−low Strobe control and a noninverting output. The HC153 is similar in function to the HC253, which has 3−state outputs.
