2 / 7 page December 1990 2 Philips Semiconductors Product specification 8-input multiplexer 74HC/HCT151 FEATURES • True and complement outputs • Multifunction capability • Permits multiplexing from n lines to 1 line • Non-inverting data path • See the “251” for the 3-state version • Output capability: standard • ICC category: MSI GENERAL DESCRIPTION The 74HC/HCT151 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. 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 CL = 15 pF; VCC =5 V In to Y, Y 1719ns Sn to Y, Y 1920ns E to Y 1213ns E to Y 1418ns CI input capacitance 3.5 3.5 pF CPD power dissipation capacitance per package notes 1 and 2 40 40 pF |
