74LVT2245 74LVTH2245 3.3 V octal transceiver with 30 termination resistors 3-state Rev. 5 10 April 2017 Product data sheet 1 General description The 74LVT2245 74LVTH2245 is a high-performance BiCMOS product designed for V CC operation at 3.3 V. This device is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The control function implementation minimizes external timing requirements. The device features an output enable input (OE) for easy cascading and a direction input (DIR) for direction control. The 74LVT2245 74LVTH2245 is designed with 30 series resistance in both the HIGH- state and LOW-state of the output. This design reduces line noise in applications such as memory address drivers, clock drivers and bus transceivers and transmitters. 2 Features and benefits 30 output termination resistors Octal bidirectional bus interface 3-state buffers Output capability: +12 mA and -12 mA TTL input and output switching levels Input and output interface capability to systems at 5 V supply Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs Live insertion and extraction permitted Power-up 3-state No bus current loading when output is tied to 5 V bus Latch-up protection: JESD78: exceeds 500 mA ESD protection: MIL STD 883 method 3015: exceeds 2000 V MM JESD22-A115-A exceeds 200 V (C = 200 pF, R = 0 )Nexperia 74LVT2245 74LVTH2245 3.3 V octal transceiver with 30 termination resistors 3-state 3 Ordering information Table 1.
