2 / 15 page  September 1993 2 Philips Semiconductors Product specification 16-channel analog multiplexer/demultiplexer 74HC/HCT4067 FEATURES • Low “ON” resistance: 80 Ω (typ.) at VCC = 4.5 V 70 Ω (typ.) at VCC = 6.0 V 60 Ω (typ.) at VCC = 9.0 V typical “break before make” built-in • Output capability: non-standard • ICC category: MSI GENERAL DESCRIPTION The 74HC/HCT4067 are high-speed Si-gate CMOS devices and are pin compatible with the “4067” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT4067 are 16-channel analog multiplexers/demultiplexers with four address inputs (S0 to S3) , an active LOW enable input (E), sixteen independent inputs/outputs (Y0 to Y15) and a common input/output (Z). The ”4067” contains sixteen bidirectional analog switches, each with one side connected to an independent input/output (Y0 to Y15) and the other side connected to a common input/output (Z). With E LOW, one of the sixteen switches is selected (low impedance ON-state) by S0 to S3. All unselected switches are in the high impedance OFF-state. With E HIGH, all switches are in the high impedance OFF-state, independent of S0 to S3. The analog inputs/outputs (Y0 to Y15, and Z) can swing between VCC as a positive limit and GND as a negative limit. VCC to GND may not exceed 10 V. 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 + CS) × VCC2 × fo} where: fi = input frequency in MHz fo = output frequency in MHz ∑ {(CL + CS) × VCC2 × fo} = sum of outputs CL = output load capacitance in pF CS = max. switch 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 SYMBOL PARAMETER CONDITIONS TYPICAL UNIT HC HCT tPZL/ tPZH turn-on time CL = 15 pF; RL =1 kΩ; VCC = 5 V E to Vos 26 32 ns Sn to Vos 29 33 ns tPLZ/ tPHZ turn-off time E to Vos 27 26 ns Sn to Vos 29 30 ns CI input capacitance 3.5 3.5 pF CPD power dissipation capacitance per switch notes 1 and 2 29 29 pF CS max. switch capacitance independent (Y) 5 5 pF common (Z) 45 45 pF |
