SN74HC14DTR

XBLW 74HC/HCT14 Hex inverter with Schmitt-trigger inputs General Description The SN74HC/HCT14 is a hex inverter with Schmitt-trigger inputs. This device features reduced input threshold levels to allow interfacing to TTL logic levels. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. Schmitt trigger inputs transform slowly changing input signals into sharply defined jitter-free output signals. Features  Input levels: For SN74HC14: CMOS level For SN74HCT14: TTL level  Low-power dissipation  Specified from -40℃ to +125℃  Packaging information: DIP14/SOP14/TSSOP14 ORDERING INFORMATION DEVICE Package Type MARKING Packing Packing QTY SN74HC14N SN74HC14DTR SN74HC14TDTR SN74HCT14N SN74HCT14DTR SN74HCT14TDTR DIP-14 SOP-14 TSSOP-14 DIP-14 SOP-14 TSSOP-14 74HC14N 74HC14 74HC14 74HCT14N 74HCT14 74HCT14 Tube Tape Tape Tube Tape Tape 1000/Box 2500/Reel 3000/Reel 1000/Box 2500/Reel 3000/Reel Block Diagram And Pin Description Block Diagram XBLW version 2.0 www.xinboleic.com Technical Support:4009682003 1 / 15 XBLW 74HC/HCT14 Hex inverter with Schmitt-trigger inputs Figure 1.
