About solderability, following conditions were confirmed • Solderability (1) Use of Sn-37Pb solder Bath · solder bath temperature = 230°C · dipping time = 5 seconds · the number of times = once · use of R-type flux (2) Use of Sn-3.0Ag-0.5Cu solder Bath · solder bath temperature = 245°C · dipping time = 5 seconds · the number of times = once · use of R-type flux 1 2007-04-04 www.DataSheet4U.com TA7522SG/FG Block Diagram and Pin Layout TA7522SG TA7522FG Note 1: The TA7522SG and TA7522FG are the same chip housed in different packages. Note 2: Some functional blocks, circuits, or constants are omitted or simplified in the block diagram to clarify the descriptions of the relevant features. 2 2007-04-04 www.DataSheet4U.com TA7522SG/FG Pin Description Pin No. TA7522SG 1 2 3 4 5 6 7 8 9 Symbol 1 2 3 ⎯ 4 5 6 7 8 Description Inverted-input pin Non-inverted-input pin Output pin corresponding to INPUT1 Output pin for inversion of OUT1 Grounded Output pin corresponding to INPUT2 + − TA7522FG INPUT1− INPUT1 OUT1 OUT1 GND OUT2 INPUT2 INPUT2 VCC + Non-inverted-input pin Inverted-input pin Power supply pin Absolute Maximum Ratings (Ta = 25°C) Characteristics Supply voltage Supply voltage surge Power dissipation Differential input voltage Input voltage Output current Operating temperature Storage temperature Symbol VCC VCC SURGE PD DVIN VIN ISINK Topr Tstg Rating Unit V V mW V V mA °C °C −0.3 to 18 +30 (within 1 sec) 500/440 ±18 −0.3 to 18 30 −40 to 85 −55 to 150 Note 1: The absolute maximum ratings of a semiconductor device are a set of specified parameter values which must not be exceeded during operation, even for an instant. If any of these levels is exceeded during operation, the device’s electrical characteristics may be irreparably altered and the reliability and lifetime of the device can no longer be guaranteed, possibly causing damage to any other equipment with which it is used. Applications using the device should be designed such that the absolute maximum ratings will never be exceeded in any operating conditions. Ensuring that the parameter values remain within these specified ranges during device operation will help to ensure that the integrity of the device is not compromised.
