MB2541 Datasheet, PDF (2/12 Pages) NXP Semiconductors – Dual octal buffer line driver 3-State

Philips Semiconductors
16-bit buffer/line drivers (3-State)
Product specification
MB2541
FEATURES
• Two 8-bit bus interfaces
• Power-up 3-State
• Multiple V_CC and GND pins minimize switching noise
• Provides ideal interface and increases fan-out of MOS
Microprocessors
• 3-State buffers sink 64mA and source 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 MB2541 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The MB2541 has two 8-bit buffers that are ideal for driving bus lines.
The outputs are all capable of sinking 64mA and sourcing 32mA.
