The VHCT14A contains six independent inverters which are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. Protection circuits ensure that 0V to 7V can be applied to the input pins without regard to the supply voltage and to the output pins with VCC 0V. These circuits prevent device destruction due to mismatched supply and input/ output voltages. This device can be used to interface 3V to 5V systems and two supply systems such as battery backup. Features s High speed: tPD 5.0 ns (typ) at TA 2.0V, VIL 25qC 0.8V s High noise immunity: VIH s Power down protection is provided on all inputs and outputs s Low noise: VOLP 1.0V (max) 25qC s Low power dissipation: ICC 2 PA (max) @ TA s Pin and function compatible with 74HCT14 Ordering Code: Order Number 74VHCT14AM 74VHCT14ASJ 74VHCT14AMTC 74VHCT14AMTCX_NL (Note 1) 74VHCT14AN Package Number M14A M14D MTC14 MTC14 N14A Package Description 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow Pb-Free 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 14-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Pb-Free 14-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Surface mount packages are also available on Tape and Reel.

The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation outside databook specifications. Note 3: HIGH or LOW state. IOUT absolute maximum rating must be observed. Note 4: VCC 0V. Note 5: VOUT GND, VOUT ! VCC (Outputs Active) Note 6: Unused inputs must be held HIGH or LOW. They may not float.
