FEATURES
DESCRIPTION
The 74LVT623 is a high-performance BiCMOS product designed for
operation at 3.3 V.
• Separate controls for data flow in each direction
V
CC
• Output capability: +64 mA/–32 mA
The 74LVT623 device is an octal transceiver featuring non–inverting
3-State bus compatible outputs in both send and receive directions.
The 74LVT623 is designed for asynchronous two-way
communication between data buses. The control function
implementation allows for maximum flexibility in timing. This device
allows data transmission from the A bus to the B bus or from the B
bus to the A bus, depending upon the logic levels at the Enable
inputs (OEBA and OEAB). The Enable inputs can be used to disable
the device so that the buses are effectively isolated.
• TTL input and output switching levels
• Input and output interface capability to systems at 5 V supply
• Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
• Live insertion/extraction permitted
• No bus current loading when output is tied to 5 V bus
• Power-up 3-State
Control of data flow from B to A is similar, but using the EBA, LEBA,
and OEBA inputs.
• Power-up reset
• Latch-up protection exceeds 500 mA per JEDEC Std 17
• ESD protection exceeds 2000 V per MIL STD 883 Method 3015
and 200 V per Machine Model

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.
3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
