【选型】圣邦微单路反相器SGM7SZ04XN5G/TR可兼容SN74LVC1GU04DBVR,引脚定义一致
在现今芯片短缺状况下,工业自动化应用中原先采用国际一线大牌的芯片,为了预防采购问题导致的生产难题,需要寻找二供。本文对TI的SN74LVC1GU04DBVR和圣邦微SGM7SZ04XN5G/TR做一个参数对比,说明两者兼容,为设计者提供参考。
主要参数对比如下:
功能框图对比:
SN74LVC1GU04DBVR:
SGM7SZ04XN5G/TR:
可以看到:
(1)两者功能逻辑相同,主要参数相似,SN74LVC1GU04DBVR传播延迟更短。
(2)封装兼容,引脚定义一致。
一般应用情况下,两者可以互为二供。

【经验】如何提高SGMICRO SGM41285在光模块APD中的工作效率?
用户反馈SGMICRO的DCDC升压变换器SGM41285用在光模块APD时的实测效率和规格效率曲线有差异,存在效率偏低情况,经过排查是因为芯片本身损耗是固定的,包括Rds-on、开关损耗、二极管损耗等,这些是不可避免的;效率测试时,输入电流是1mA量级,建议使用6位半万用表或相近精度的电流表,以排除测量因素的影响。
