GENERAL DESCRIPTION
74HC/HCT151 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 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”. input capacitance power dissipation capacitance per package notes 1 and 2 CONDITIONS HC CL = 15 pF; VCC = 5 V 17 19 12 14 3.5 40 19 20 13 18 3.5 40 ns ns ns ns pF pF HCT UNIT December 1990 2 Philips Semiconductors Product specification 8-input multiplexer PINDESCRIPTION
