Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild_questions@onsemi.com.

The device is nibble controlled. Individual 3-STATE control inputs can be shorted together for 8-bit or 16-bit operation. ■ Input and output interface capability to systems at 5V VCC The LVT162244 and LVTH162244 are designed with equivalent 25: series resistance in both the HIGH and LOW states of the output. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus transceivers/transmitters. The LVTH162244 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs. These buffers and line drivers are designed for low-voltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The LVT162244 and LVTH162244 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining a low power dissipation. ■ Bushold data inputs eliminate the need for external pullup resistors to hold unused inputs (74LVTH162244), also available without bushold feature (74LVT162244). ■ Live insertion/extraction permitted ■ Power Up/Power Down high impedance provides glitchfree bus loading ■ Outputs include equivalent series resistance of 25: to make external termination resistors unnecessary and reduce overshoot and undershoot ■ Functionally compatible with the 74 series 162244 ■ Latch-up performance exceeds 500 mA ■ ESD performance: Human-body model ! 2000V Machine model ! 200V Charged-device ! 1000V ■ Also packaged in plastic Fine-Pitch Ball Grid Array (FBGA) Ordering Code: Order Number 74LVT162244G (Note 1)(Note 2) Package Number BGA54A Package Description 54-Ball Fine-Pitch Ball Grid Array (FBGA), JEDEC MO-205, 5.5mm Wide 74LVT162244MEA (Note 2) MS48A 48-Lead Small Shrink Outline Package (SSOP), JEDEC MO-118, 0.300" Wide 74LVT162244MTD (Note 2) MTD48 48-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 6.1mm Wide 74LVTH162244G (Note 1)(Note 2) BGA54A 54-Ball Fine-Pitch Ball Grid Array (FBGA), JEDEC MO-205, 5.5mm Wide 74LVTH162244MEA MS48A 48-Lead Small Shrink Outline Package (SSOP), JEDEC MO-118, 0.300" Wide [Tube] 74LVTH162244MEX MS48A 48-Lead Small Shrink Outline Package (SSOP), JEDEC MO-118, 0.300" Wide [Tape and Reel] 74LVTH162244MTD MTD48 48-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 6.1mm Wide [Tube] 74LVTH162244MTX MTD48 48-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 6.1mm Wide [Tape and Reel] Note 1: Ordering code “G” indicates Trays.
