Functional DescriptionThe 74VCX16839 consists of twenty selectable non-invert-ing buffers or registers with word wide modes. Mode func-tionality is selected through operation of the CLK andREGE pin as shown by the truth table. When REGE is heldat a logic HIGH the device operates as a 20-bit register.Data is transferred from I to O on the rising edge of then nCLK input. When the REGE pin is held at a logic LOW thedevice operates in a flow through mode and data propa-gates directly from the I to the O outputs. All outputs cann nbe 3-stated by holding the OE pin at a logic HIGH.Logic Diagram 274VCX1683974VCX16839Absolute Maximum Ratings(Note 2) Recommended Operating Conditions (Note 4)Supply Voltage (V ) −0.5V to +4.6VCCDC Input Voltage (V ) −0.5V to +4.6V Power SupplyIOutput Voltage (V ) Operating 1.65V to 3.6VOOutputs 3-STATE −0.5V to +4.6V Data Retention Only 1.2V to 3.6VOutputs Active (Note 3) −0.5V to V +0.5V Input Voltage −0.3V to +3.6VCCDC Input Diode Current (I ) V < 0V −50 mA Output Voltage (V )IK I ODC Output Diode Current (I ) Output in Active States 0V to VOK CCV < 0V −50 mA Output in “OFF” State 0V to 3.6VOV > V +50 mA Output Current in I /IO CC OH OLDC Output Source/Sink Current V = 3.0V to 3.6V ±24 mACC(I /I ) ±50 mA V = 2.3V to 2.7V ±18 mAOH OL CCDC V or GND Current per V = 1.65V to 2.3V ±6 mACC CCSupply Pin (I or GND) ±100 mA Free Air Operating Temperature (T ) −40°C to +85°CCC AStorage Temperature Range (T ) −65°C to +150°C Minimum Input Edge Rate (∆ t/∆ V)STGV = 0.8V to 2.0V, V = 3.0V 10 ns/VIN CCNote 2: The Absolute Maximum Ratings are those values beyond whichthe safety of the device cannot be guaranteed. The device should not beoperated at these limits. The parametric values defined in the ElectricalCharacteristics tables are not guaranteed at the Absolute Maximum Rat-ings. The “Recommended Operating Conditions” table will define the condi-tions for actual device operation.Note 3: I Absolute Maximum Rating must be observed.ONote 4: Floating or unused inputs must be held HIGH or LOW.DC applications with I/O compatibility up to 3.6V.
