PI5L102LE

PI5L102 CompactPCI™ Hot Swap Pull-up Switch Description Features • Supports CompactPCI™ precharge voltage selection • 3.3V/2.7kΩ, 5V/1ohm line termination selection • Ultra-low quiescent current: 0.1μA typical • Low On-Resistance: 7Ω maximum • Single supply operation up to 6.2V ±5% • Wide bandwidth data rates: >200 Mbps • Mechanical relay replacement • Packaging (Pb-free & Green available): The PI5L102L CompactPCI Hot Swap Pull-up switch is a Quad 1:2 multiplexer. It is designed to switch the 1V precharge bias voltage and 10kΩ pull-up resistor connected to the CompactPCI bus signals during Hot Swap. Each switch can connect eight inputs (IAn to IDn) to a given pull-up voltage level. In addition, the PI5L102 can be used to select 2.7 kΩ/3.3V or 1.0 kohm/5V pull-ups for the system card PCI signal lines. ON resistance is a low 7Ω maximum and all eight switches are selected or disabled with a single CMOS/TTL compatible signal. For general-purpose applications, the PI5L102 can replace mechanical relays. In network systems, physical layer signals can be switched. To reduce the insertion loss, the PI5L102 can be powered by a 6.2V Zener diode. -Compact 20-pin TSSOP (L) Pin Configuration Block Diagram )! )! )" )" )# )# )$ )$ % 9! 9" 9# 9$   .# .#   6## )!   % )!   )$ 9!   )$ )"   9$ )"   )# 9"   )# '.$   9#   .# .# Truth Table(1) Pin Description E YA YB YC YD Function H Hi-Z HI-Z Hi-Z HI-Z Disable L .# IA0, IA1 IB0, IB2 IC0, IC1, ID0, ID1 Pin Name IAn-IDn E YA-YD GND VCC Enable Note: 1.

For example, given a +5.0V supply, E may be driven low to 0V and high to 5.5V. Driving E Rail-to-Rail® minimizes power consumption. To keep RON to a minimum, it is recommended that the VCC voltage be increased to a voltage between +6.0V and +6.5V (see Figure 5). The RON vs VIN curve shows the effect of On-Resistance and input voltage which is exponential. Ideally an input voltage between 0.2V and 3.6V will keep RON in the flat part of the curve (ΔRON or flatness is ~2ohm). Power-Supply Sequencing Proper power-supply sequencing is recommended for all CMOS devices. Always apply VCC before applying signals to the input/ output or control pins. 6 6)/ 6)/ 6 0)!, 0)!, %NABLE6 %NABLE6 K7 &ROMC0#) #ONNECTOR 7 K7 0ERICOM 0#) "RIDGE 0)# 0ULLUP2EQUIREDON%ACHC0#),INE Figure 1.
