UCD4043B中文资料CMOS QUAD 3-STATE NOR R/S LATCHES数据手册UTC规格书

描述 Description

UTC UCD4043B types are quad cross-coupled 3-state CMOS NOR latches.  Each latch has a separate Q output and  individual SET and RESET inputs. The Q outputs are controlled by a common  ENABLE  input.  A logic  high  on   the  ENABLE input connects the latch states to the Q outputs.  A logic low on the ENABLE input disconnects the latch  states from the Q outputs,  resulting in an open circuit condition on the Q outputs.  The open circuit feature allows common bussing of the outputs.

特性 Features

3-state outputs with common output ENABLE Separate SET and RESET inputs for each latch NOR configurations 5V, 10Vr and 15V parametric ratings Standardized symmetrical output characteristics Maximum input current of 1uA at 18V over full package temperature range; 100nA at 18V and 25°C
