The Nexperia 74HC85D.652 is a 4-bit magnitude comparator with 3-state outputs. It has four data inputs, A0 through A3, allowing it to compare up to four bits of data. The output of the part is presented on four pins, L0 through L3, which each output either a high, a low, or a high-impedance state, depending on the input data. This device uses CMOS technology for low power consumption. It is capable of both high and low noise operation, with high noise immunity up to VCC = 5.5V and low noise immunity up to VCC = 2.0V. It is also specified for operation over an industrial temperature range of -40°C to 125°C.
