LVMDM-7G Datasheet, PDF (1/1 Pages) Rhombus Industries Inc. – LVMDM Series LVC Low Voltage Logic Buffered 5-Tap Delay SMD Modules

LVMDM Series LVC Low Voltage Logic Inputs accept voltages up to 5.5 V
74LVC type input can be driven from either 3.3V or 5V
Buffered 5-Tap Delay SMD Modules ^{devices. This allows delay module to serve as a}
translator in a mixed 3.3V / 5V system environment.
