74ABT16825A Datasheet, PDF (2/10 Pages) NXP Semiconductors – 18-bit buffer/line driver; non-inverting 3-State

Philips Semiconductors
18-bit buffer/line driver; non-inverting (3-State)
Product specification
74ABT16825A
74ABTH16825A
FEATURES
• Multiple V_CC and GND pins minimize switching noise
• Live insertion/extraction permitted
• 3-State output buffers
• Power-up 3-State
• 74ABTH16825A incorporates bus-hold data inputs which
eliminate the need for external pull-up resistors to hold unused
inputs
• Output capability: +64mA/–32mA
• Latch-up protection exceeds 500mA per Jedec Std 17
• ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 200V per Machine Model
• Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs

DESCRIPTION
The74ABT16825A high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The74ABT16825A 18-bit buffers provide high performance bus
interface buffering for wide data/address paths or buses carrying
parity. They have NOR Output Enables (nOE1, nOE2) for maximum
control flexibility.
Two options are available, 74ABT16825A which does not have the
bus-hold feature and 74ABTH16825A which incorporates the
bus-hold feature.
