Product Summary
The SN7438DR is a quadruple 2-input positive-nand buffer with open-collector outputs which contains four independent 2-input NAND buffer gates with open-collector outputs. The open-collector outputs require pull-up resistors to perform correctly. The SN7438DR may be connected to other open-collector outputs to implement active-low wired-OR or active-high wired-AND functions. Open-collector device is often used to generate high VOH levels.
Parametrics
SN7438DR absolute maximum ratings: (1)Supply voltage, VCC: 7V; (2)Input voltage: 5.5V; (3)Off-state output voltage: -55 to +125℃; (4)Operating free-air temperature range: 0 to 70℃; (5)Storage temperature range: -65 to +150℃.
Features
SN7438DR features: (1)package options include plastic "small outline" packages, ceramic chip carriers and flat packages, and plastic and ceramic dips; (2)Dependable texas instruments quality and reliability.
