M74HCT373

The M54/74HCT373 and M54HCT533 are high speed CMOS OCTAL LATCH WITH 3-STATE OUTPUTS fabricated with in silicon gate C²MOS technology.

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 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 non inverting outputs. The three state output configuration and the wide choise of outline make bus organized system simple.

These integrated circuits have input and output characteristics that are fully compatible with 54/74 LSTTL logic families. M54/74HCT devices are designed to directly interface HSC²MOS systems with TTL and NMOS components. They are also plug in replacements for LSTTL devices giving a reduction of power consumption. All inputs are equipped with protection circuits against discharge and transient excess voltage.
