INTEGRATED CIRCUITS DATA SHEET For a complete data sheet, please also download: The IC06 74HC/HCT/HCU/HCMOS Logic Family Specifications The IC06 74HC/HCT/HCU/HCMOS Logic Package Information The IC06 74HC/HCT/HCU/HCMOS Logic Package Outlines 74HC/HCT151 8-input multiplexer Product specication File under Integrated Circuits, IC06 December 1990 Philips Semiconductors Product specication 8-input multiplexer 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 74HC/HCT151 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 TYPICAL SYMBOL tPHL/ tPLH PARAMETER propagation delay In to Y, Y Sn to Y, Y E to Y E to Y CI CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in W): 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”. input capacitance power dissipation capacitance per pack……
