74LVT2245; 74LVTH2245
3.3 V octal transceiver with 30 Ω termination resistors; 3-state
Rev. 04 — 24 April 2006
Product data sheet
1. General description
The 74LVT2245; 74LVTH2245 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 input (OE) for easy
cascading and a direction input (DIR) for direction control.
The 74LVT2245; 74LVTH2245 is designed with 30 Ω 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
30 Ω 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:
u JESD78: exceeds 500 mA
n ESD protection:
u MIL STD 883 method 3015: exceeds 2000 V
u Machine model: exceeds 200 V
