74LVT640 3.3 V Octal transceiver with direction pin inverting 3-state Rev. 3 10 April 2017 Product data sheet 1 General description The 74LVT640 is a high-performance BiCMOS product designed for V operation CC at 3.3 V. This device is an octal transceiver featuring 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 (OE) input for easy cascading and a direction (DIR) input for direction control. 2 Features and benefits 3-state buffers Octal bidirectional bus interface Input and output interface capability to systems at 5 V supply TTL input and output switching levels Output capability: +64 mA and -32 mA Bus-hold data inputs eliminate the need for external pull-up resistors for unused inputs Live insertion/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 VNexperia 74LVT640 3.3 V Octal transceiver with direction pin inverting 3-state 3 Ordering information Table 1.
