1. General description
The 74LVT245B 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 (OE) input for easy
cascading and a direction (DIR) input for direction control.
2. Features
n 3-state buffers
n Octal bidirectional bus interface
n Input and output interface capability to systems at 5 V supply
n TTL input and output switching levels
n Output capability: +64 mA/−32 mA
n Latch-up protection exceeds 500 mA per JEDEC Std 17
n ESD protection:
u HBM JESD22-A114E exceeds 2000 V
u MM JESD22-A115-A exceeds 200 V
n Bus-hold data inputs eliminate the need for external pull-up resistors for unused inputs
n Live insertion/extraction permitted
n Power-up 3-state
n No bus current loading when output is tied to 5 V bus
