This device contains six independent inverters and performs the Boolean function Y = A. Inputs can be driven from either 3.3V or 5V devices. This feature allows the use of this device as a translator in a mixed 3.3V/5V supply system. The LVC14A has been designed with a ±24mA output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance. APPLICATIONS: Drive Features for LVC14A: – High Output Drivers: ±24mA – Reduced system switching noise • 5V and 3.3V mixed voltage systems • Data communication and telecommunication systems FUNCTIONAL BLOCK DIAGRAM A PIN CONFIGURATION Y 1A 1 14 V CC 1Y 2 13 6A 2A 3 12 6Y 2Y 4 11 5A 3A 5 10 5Y 3Y 6 9 4A GND 7 8 4Y SO14-1 SO14-2 SO14-3 SOIC/ SSOP/ TSSOP TOP VIEW FUNCTION TABLE (each inverter) Inputs xA (1) PIN DESCRIPTION Outputs xY H L Pin Names xA L H xY Description Inputs Outputs NOTE: 1.
