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 device is byte controlled. Each byte has separate control inputs which can be shorted together for full 16-bit operation. The T/R inputs determine the direction of data flow through the device. The OE inputs disable both the A and B ports by placing them in a high impedance state. The LVT162245 and LVTH162245 are designed with equivalent 25: series resistance in both the HIGH and LOW states on the A Port outputs. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus transceivers/transmitters. ■ Input and output interface capability to systems at 5V VCC The LVTH162245 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs. These non-inverting transceivers are designed for low voltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The LVT162245 and LVTH162245 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 (74LVTH162245), also available without bushold feature (74LVT162245). ■ Live insertion/extraction permitted ■ Power Up/Down high impedance provides glitch-free bus loading ■ A Port outputs include equivalent series resistance of 25: making external termination resistors unnecessary and reducing overshoot and undershoot ■ A Port outputs source/sink r12 mA. B Port outputs source/sink 32 mA/64 mA ■ Functionally compatible with the 74 series 162245 ■ Latch-up performance exceeds 500 mA ■ ESD performance: Human-body model ! 2000V Machine model ! 200V Charged-device model ! 1000V ■ Also packaged in plastic Fine Pitch Ball Grid Array (FBGA) Ordering Code: Order Number 74LVT162245G (Note 1)(Note 2) Package Number BGA54A (Preliminary) Package Description 54-Ball Fine-Pitch Ball Grid Array (FBGA), JEDEC MO-205, 5.5mm Wide 74LVT162245MEA (Note 2) MS48A 48-Lead Small Shrink Outline Package (SSOP), JEDEC MO-118, 0.300" Wide 74LVT162245MTD (Note 2) MTD48 48-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 6.1mm Wide 74LVTH162245G (Note 1)(Note 2) BGA54A 54-Ball Fine-Pitch Ball Grid Array (FBGA), JEDEC MO-205, 5.5mm Wide 74LVTH162245MEA MS48A 48-Lead Small Shrink Outline Package (SSOP), JEDEC MO-118, 0.300" Wide [TUBE] 74LVTH162245MEX MS48A 48-Lead Small Shrink Outline Package (SSOP), JEDEC MO-118, 0.300" Wide [TAPE and REEL] 74LVTH162245MTD MTD48 48-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 6.1mm Wide [TUBE] 74LVTH162245MTX 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.
