Low Voltage Octal Bidirectional Transceiver with
3-STATE Inputs/Outputs and 25
Series Resistors in the
B Port Outputs
Features
■ Input and output interface capability to systems at
5V VCC
■ Equivalent 25
series resistor on B Port outputs
■ Bushold data inputs eliminate the need for external
pull-up resistors to hold unused inputs (74LVTH2245),
also available without bushold feature (74LVT2245)
■ Live insertion/extraction permitted
■ Power Up/Down high impedance provides glitch-free
bus loading
■ Outputs source/sink –12mA/+12mA on B Port,
–32mA/+64mA on A Port
■ Latch-up performance exceeds 500mA
■ ESD performance:
– Human-body model
> 2000V
– Machine model
> 200V
– Charged-device model
> 1000V
General Description
The LVT2245 and LVTH2245 contain eight non-inverting
bidirectional buffers with 3-STATE outputs and are
intended for bus-oriented applications. The Transmit/
Receive (T/R) input determines the direction of data flow
through the bidirectional transceiver. Transmit (active-
HIGH) enables data from A Ports to B Ports; Receive
(active-LOW) enables data from B Ports to A Ports. The
Output Enable input, when HIGH, disables both A and B
Ports by placing them in a high impedance state. The
equivalent 25
-series resistor in the B Port helps reduce
output overshoot and undershoot.
The LVTH2245 data inputs include bushold, eliminating
the need for external pull-up resistors to hold unused
inputs.
These transceivers are designed for low voltage (3.3V)
VCC applications, but with the capability to provide a TTL
interface to a 5V environment. The LVT2245 and
LVTH2245 are fabricated with an advanced BiCMOS
technology to achieve high speed operation similar to 5V
ABT while maintaining low power dissipation.
