FEATURES · Output capability: bus driver · ICC category: MSI GENERAL DESCRIPTION
74HC/HCT241
The 74HC/HCT241 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. The 74HC/HCT241 are octal non-inverting buffer/line drivers with 3-state outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE.

1. CPD is used to determine the dynamic power dissipation (PD in µW): PD = CPD × VCC2 × fi + (CL × VCC2 × fo) where: fi = input frequency in MHz fo = output frequency in MHz (CL × VCC2 × fo) = sum of outputs CL = output load capacitance in pF VCC = supply voltage in V 2. For HC the condition is VI = GND to VCC For HCT the condition is VI = GND to VCC - 1.5 V ORDERING INFORMATION See "74HC/HCT/HCU/HCMOS Logic Package Information".
