INTEGRATED CIRCUITS DATA SHEET 74HC1G66; 74HCT1G66 Bilateral switch Product specication Supersedes data of 2001 Mar 02 2002 May 15 Philips Semiconductors Product specication Bilateral switch FEATURES Wide operating voltage range from 2.0 to 9.0 V Very low ON-resistance: – 45 (typical) at VCC = 4.5 V – 30 (typical) at VCC = 6.0 V – 25 (typical) at VCC = 9.0 V. High noise immunity Low power dissipation Very small 5 pins package Output capability: non standard. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6.0 ns. DESCRIPTION 74HC1G66; 74HCT1G66 The 74HC1G/HCT1G66 is a high-speed Si-gate CMOS device. The 74HC1G/HCT1G66 provides an analog switch. The switch has two input/output pins (Y and Z) and an active HIGH enable input pin (E). When pin E is LOW, the analog switch is turned off. The non standard output currents are equal compared to the 74HC/HCT4066. TYPICAL SYMBOL tPZH/tPZL tPHZ/tPLZ CI CPD CS Notes 1. CPD is used to determine the dynamic power dissipation (PD in W). PD = CPD × VCC2 × fi + ∑ ((CL +CS)× VCC2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; CS = maximum switch capacitance in pF; VCC = supply voltage in Volts; ∑ ((CL +CS)× VCC2 × fo) = sum of outputs. 2. For HC1G the condition is VI = GND to VCC. For HCT1G the condition is VI = GND to VCC 1.5 V. FUNCTION TABLE See note 1. INPUT E L H Note 1. H = HIGH voltage level; L = LOW voltage level. 2002 May 15 2 SWITCH OFF ON PARAMETE……
