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
I 30 Ω output termination resistors
I Octal bidirectional bus interface
I 3-state buffers
I Output capability: +12 mA and −12 mA
I TTL input and output switching levels
I Input and output interface capability to systems at 5 V supply
I Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs
I Live insertion and extraction permitted
I Power-up 3-state
I No bus current loading when output is tied to 5 V bus
I Latch-up protection:
N JESD78: exceeds 500 mA
I ESD protection:
N MIL STD 883 method 3015: exceeds 2000 V
N Machine model: exceeds 200 V

[3] This is the bus hold overdrive current required to force the input to the opposite logic state.
[4] This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 ms. From VCC = 1.2 V to VCC = 3.0 V to 3.6 V
a transition time of 100 µs is permitted.
