NLSF2500 Keypad Multiplexer The NLSF2500 is a keyboard multiplexer fabricated in sub−micron silicon CMOS Technology. The NLSF2500 is designed to operate over wide operating voltage, with minimum power consumption and very low voltage drop from VCC. The device saves dozens of active and passive components and permits operating voltage far lower than the standard diode scheme. http://onsemi.com Features Typical Applications MARKING DIAGRAM ÇÇ ÇÇ 16 1 NLSF 2500 ALYW G QFN−16 CASE 485AE XXXX A L Y W G • Cell Phones • PDAs • MP3 players = Specific Device Code = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package 8 IN5 5 IN2 PIN CONNECTIONS 7 IN4 • • • Single Supply Operation Optimized for 1.8 V to 3.6 V VCC Tiny 3 x 3 mm QFN−16 Package Conforms to: JEDEC MO−220, Issue H, Variation VEED−6 Very Low Voltage Drop Permits Operation Down to 1.65 V Near Zero Static Power ESD Protection: Human Body Model (HBM); > 3000 V, Machine Model (MM); >300 V Latchup Maximum Rating: 200 mA Pin−to−Pin Compatible with CM2500 This is a Pb−Free Device 6 IN3 • • • • • • • • IN1 4 VCC 9 NC 10 GND 3 OUT4 13 OUT3 14 12 OUT5 OUT2 15 11 OUTB NC 1 OUT1 16 OUTA 2 Bottom View ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 4 of this data sheet. © Semiconductor Components Industries, LLC, 2006 June, 2006 − Rev. 2 1 Publication Order Number: NLSF2500/D NLSF2500 GND IN1 IN2 R IN3 R IN4 R IN5 R VCC Ax R IN IN IN IN IN B A B A B A B A B A INx Bx N1 R R R R R R N2 R GND OUTA OUT1 OUT2 OUT3 OUT4 OUT5 OUTB Figure 1.
