2 / 8 page September 1993 2 Philips Semiconductors Product specification Octal buffer/line driver; 3-state 74HC/HCT241 FEATURES • Output capability: bus driver • ICC category: MSI GENERAL DESCRIPTION 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. QUICK REFERENCE DATA GND = 0 V; Tamb =25 °C; tr =tf = 6 ns Notes 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”. SYMBOL PARAMETER CONDITIONS TYPICAL UNIT HC HCT tPHL/ tPLH propagation delay 1An to 1Yn; 2An to 2Yn CL = 15 pF; VCC = 5 V 7 11 ns CI input capacitance 3.5 3.5 pF CPD power dissipation capacitance per buffer notes 1 and 2 30 30 pF |
