LVITD-12 Datasheet, PDF (1/1 Pages) Rhombus Industries Inc. – LVITD Series LVC Low Voltage Logic 10-Tap Delay Modules
LVITD Series LVC Low Voltage Logic 10-Tap Delay Modules
Inputs accept voltages up to 5.5 V
74LVC type input can be driven from either 3.3V or 5V
devices. This allows delay module to serve as a
translator in a mixed 3.3V / 5V system environment.
