54HC154F3A Renesas

The 54HC154F3A is an 8-bit bus-oriented multiplexer produced by Renesas Electronics. It is a CMOS device with two 4 to 1 multiplexers, two 2 to 1 multiplexers, two 2 bit selectors, and four 1 bit selectors. The device contains two 4-channel select inputs (S0, S1) and two 2-channel select inputs (S2, S3). It can be used for digital systems where multiplexing is required. With two 4-channel select inputs and two 2-channel select inputs, the device can multiplex up to 8 data inputs. The device is made up of an 8-bit CMOS latch, and the data output is available on both the positive and negative logic terminals making it suitable for both open-collector and bipolar-based logic systems. The device is suitable for use in high-speed applications as it features a maximum propagation delay of 18ns and an output enable time of 10ns. The device also features input and output Schmitt-Triggers, which can be used to reduce noise in the system. All of the inputs and outputs are TTL compatible, making the device suitable for interfacing to both TTL and CMOS logic devices.
