These ICs achive the high speed operation similar to equivalent LSTTL while maintaning the CMOS low power dissipation. These 8 bit D-Type latches are controlled by a latch enable input (LE) and a output enable input (OE). While the LE input is held at a high level, the Q outputs will follow the data input precisely or inversely. When the LE is taken low, the Q outputs will be latched precisely or inversely at the logic level of D input data. While the OE input is at low level, the eight outputs will be in a normal logic state (high PIN CONNECTION (top view) HCT373 HCT533 ORDER CODES : M54HCTXXXF1R M74HCTXXXM1R M74HCTXXXB1R M74HCTXXXC1R or low logic level) and while high level the outpts will be in a high impedance state. The application designer has a choise of combination of inverting and ...
