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 Semiconductors 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 byte Bushold data inputs eliminate the need for external pull- controlled. Each byte has separate control inputs which up resistors to hold unused inputs (74LVTH162245), can be shorted together for full 16-bit operation. The T/R also available without bushold feature (74LVT162245). inputs determine the direction of data flow through the Live insertion/extraction permitted device. The OE inputs disable both the A and B ports by Power Up/Down high impedance provides glitch-free placing them in a high impedance state. bus loading The LVT162245 and LVTH162245 are designed with A Port outputs include equivalent series resistance of equivalent 25: series resistance in both the HIGH and 25: making external termination resistors unnecessary LOW states on the A Port outputs. This design reduces line and reducing overshoot and undershoot noise in applications such as memory address drivers, clock drivers, and bus transceivers/transmitters. A Port outputs source/sink r12 mA. B Port outputs source/sink 32 mA/ 64 mA The LVTH162245 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused Functionally compatible with the 74 series 162245 inputs. Latch-up performance exceeds 500 mA These non-inverting transceivers are designed for low volt- ESD performance: age (3.3V) V applications, but with the capability to pro- CC Human-body model 2000V vide a TTL interface to a 5V environment. The LVT162245 Machine model 200V and LVTH162245 are fabricated with an advanced Charged-device model 1000V BiCMOS technology to achieve high speed operation simi- lar to 5V ABT while maintaining a low power dissipation.
