16-bit transceiver with dual enable, non-inverting
(3-State)
Product specification
MB2623
FEATURES
• Two 8-bit bidirectional bus interfaces
• 3-State buffers
• Power-up 3-State
• Multiple V_CC and GND pins minimize switching noise
• Output capability: +64mA/–32mA
• Latch-up protection exceeds 500mA per Jedec Std 17
• ESD protection exceeds 2000 V per MIL STD 883 Method 3015
and 200 V per Machine Model
• Inputs are disabled during 3-State mode
DESCRIPTION
The MB2623 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The MB2623 is a 16-bit transceiver featuring non-inverting 3-State
bus compatible outputs in both send and receive directions. The
MB2623 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 (nOEBA and nOEAB). The Enable inputs can
be used to disable the device so that the buses are effectively
isolated.
