Description

The M54/74HCT240PU, HCT241PU and HCT244PU are high speed CMOS OCTAL BUS BUFFERs fabricated in silicon gate C2MOS technology.

M54/74HCT240PU, HCT241PU and HCT244PU have the same high speed performance of their non-PU counterpart, plus a unique input topology which incorporates a constant current source for each data input. This results is in a small IIL (-150 mA Typ.) wich can fix any data input in the HIGH Logic Level when it is left floating, thus eliminating the need of external pull-up resistor network.

This M54/74HCT240PU, HCT241PU and HCT244PU feature makes these devices particularly suitable in all applications where a data bus needs to beinterfaced tomanual controls like: rotary selectors,keyboards, dip-switches, etc. The inputs are compatible with TTL, NMOS and CMOS output voltage levels. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.

M54/74HCT240PU, HCT241PU and HCT244PU All inputs are equipped with protection circuits against static discharge and transient excess voltage.
