It can be used as an analog switch or as a low-delay bus switch. Specified over a wide operating power supply voltage, 1.65V to 5.5V, the PI5A4765 has a low On-Resistance of 0.6Ω @ 2.7V. CMOS Technology for Bus and Analog Applications Low On-Resistance: 0.6Ω @ 2.7V. Wide VCC Range: 1.65V to 5.5V Rail-to-Rail Signal Range Control Input Overvoltage Tolerance: 5.5V min. High Off Isolation: -50dB Crosstalk Rejection Reduces Signal Distortion: -80dB Break-Before-Make Switching Extended Industrial Temperature Range: –40°C to 85°C Packaging (Pb-free & Green available): -12-ball CSP Break-before-make switching prevents both switches being enabled simultaneously. This eliminates signal disruption during switching. The control input, INX, tolerates input drive signals up to 6.0V, independent of supply voltage. The PI5A4765 offers a headphone & mute detection function through utilization of an on-chip comparator. When the negative terminal of the comparator (COMP-) is less than the threshold (internally set to VCC/3, COMP0 (comparator output) is a logic high. A logic low on COMP0 occurs when COMP- rises above the the threshold. Applications • Cell Phones • PDAs • MP3 players • Portable Instrumentation • Computer Peripherals • Speaker Headset Switching PI5A4765 also offers shunt switches connected to ground in order to dissipate capacitance that builds up on the unconnected NC or NO line. As a result, reduction of popping and clicking sounds is achieved when switching between audio sources. • Power Routing • Relay Replacement • Audio/Video Signal Routing • PCMCIA Cards • Modems Pin Configuration / Block Diagram (top view) Pin Description Pin # Pin # CSP Name A1, C1 B1 A3, C3 B4 A2, C2 B2 B3 A4, C4 NOX VCC NCX GND COMX COMP0 COMPINX NO2 Description Data Port (Normally open) Positive Power Supply Data Port (Normally closed) Ground Common Output/Data Port Comparator Output Comparator Input Logic Control VCC B1 C1 COM2 C2 COMP0 B2 NC2 C3 - + B3 COMP- Function Table Note: 1. x = 1, or 2 NO1 A2 COM1 A3 NC1 A4 IN1 SHUNT SWITCH Note: 1. x = 1, or 2 Logic Input (INX) 0 1 A1 IN2 Function NCX Connected to COMX NOX Connected to COMX B4 C4 VCC 3 GND VCC MUTE 1 P-0.9 08/02/05 www.DataSheet4U.com ADVANCE INFORMATION - COMPANY CONFIDENTIAL PI5A4765 Low Volt.
