LM556

UNISONIC TECHNOLOGIES CO., LTD LM556 LINEAR INTEGRATED CIRCUIT DUAL TIMER  DESCRIPTION The UTC LM556 dual monolithic circuit is a highly stable controller capable of producing accurate delays or oscillation. The UTC LM556 is the dual of UTC NE555; timing is provided an external resistor and capacitor for each function. The two timers operate independently of each other, sharing only VCC and GND. The circuits may be triggered and reset on falling wave forms. The output structures may sink or source 200mA.  FEATURES *High Current Driver Capability(=200mA) *Adjustable Duty Cycle *Timing From μSec to Hours *Temperature Stability of 0.005%/C *TTL Compatible *Operates in Both Astable and Monostable Modes  ORDERING INFORMATION Ordering Number Lead Free Halogen Free LM556L-D14-T LM556G-D14-T - LM556G-S14-R Package DIP-14 SOP-14 Packing Tube Tape Reel  MARKING DIP-14 SOP-14 www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 3 QW-R106-004.D LM556  BLOCK DIAGRAM LINEAR INTEGRATED CIRCUIT UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 3 QW-R106-004.D LM556 LINEAR INTEGRATED CIRCUIT  ABSOLUTE MAXIMUM RATINGS (TA=25°C, unless otherwise specified) PARAMETER SYMBOL RATINGS Supply Voltage Power Dissipation VCC 16 PD 600 Lead Temperature(soldering 10 sec.)
