The device is nibble con- up resistors to hold unused inputs (74LVTH162244), trolled. Individual 3-STATE control inputs can be shorted also available without bushold feature (74LVT162244). together for 8-bit or 16-bit operation. Live insertion/extraction permitted The LVT162244 and LVTH162244 are designed with Power Up/Power Down high impedance provides glitch- equivalent 25Ω series resistance in both the HIGH and free bus loading LOW states of the output. This design reduces line noise in Outputs include equivalent series resistance of 25Ω to applications such as memory address drivers, clock driv- make external termination resistors unnecessary and ers, and bus transceivers/transmitters. reduce overshoot and undershoot The LVTH162244 data inputs include bushold, eliminating Functionally compatible with the 74 series 162244 the need for external pull-up resistors to hold unused inputs.Latch-up performance exceeds 500 mA These buffers and line drivers are designed for low-voltageESD performance: (3.3V) V applications, but with the capability to provide a CC Human-body model > 2000V TTL interface to a 5V environment. The LVT162244 and Machine model > 200V LVTH162244 are fabricated with an advanced BiCMOS Charged-device > 1000V technology to achieve high speed operation similar to 5V Also packaged in plastic Fine-Pitch Ball Grid Array ABT while maintaining a low power dissipation.
