74LVT245B  
3.3 V octal transceiver with direction pin (3-state)  
Rev. 02 — 8 May 2008  
Product data sheet  
1. General description  
The 74LVT245B is a high-performance BiCMOS product designed for VCC 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 (OE) input for easy  
cascading and a direction (DIR) input for direction control.  
2. Features  
I 3-state buffers  
I Octal bidirectional bus interface  
I Input and output interface capability to systems at 5 V supply  
I TTL input and output switching levels  
I Output capability: +64 mA/32 mA  
I Latch-up protection exceeds 500 mA per JEDEC Std 17  
I ESD protection:  
N HBM JESD22-A114E exceeds 2000 V  
N MM JESD22-A115-A exceeds 200 V  
I Bus-hold data inputs eliminate the need for external pull-up resistors for unused inputs  
I Live insertion/extraction permitted  
I Power-up 3-state  
I No bus current loading when output is tied to 5 V bus
