The 3-state outputs are Non-inverting outputs controlled by the output enable inputs OE and OE . 1 2 Output capability: bus driver A HIGH on OE causes the outputs to assume a high n impedance OFF-state. I category: MSI CC The 541 is identical to the 540 but has non-inverting outputs. GENERAL DESCRIPTION The 74HC/HCT541 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.

C is used to determine the dynamic power dissipation (P in W): PD D 2 2 P = C V f + (C V f ) where: D PD CC i L CC o f = input frequency in MHz i f = output frequency in MHz o 2 (C V f ) = sum of outputs L CC o C = output load capacitance in pF L V = supply voltage in V CC 2. For HC the condition is V = GND to V I CC For HCT the condition is V = GND to V - 1.5 V I CC ORDERING INFORMATION See 74HC/HCT/HCU/HCMOS Logic Package Information. December 1990 2
