Philips Semiconductors
16-bit transceiver with direction pins (3-State)
Product specification
MB2245
FEATURES
• 16-bit bidirectional bus interface
• Power–up 3-State
• Multiple V_CC and GND pins minimize switching noise
• 3-State buffers
• Output capability: +64 mA/–32mA
• Latch-up protection exceeds 500mA per Jedec Std 17
• ESD protection exceeds 2000 V per MIL STD 883 Method 3015
and 200V per Machine Model
• Inputs are disabled during 3-State mode
DESCRIPTION
The MB2245 high-performance BiCMOS device combines low static
and dynamic power dissipation with high speed and high output
drive.
The MB2245 device is a 16-bit 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 two Output Enable (1OE, 2OE)
inputs for easy cascading and two Direction (1DIR, 2DIR) inputs for
direction control.
