DESCRIPTION
The 74ABT16374B high-performance BiCMOS device combines
low static and dynamic power dissipation with high speed and high
output drive.
The 74ABT16374B has two 8-bit, edge triggered registers, with each
register coupled to eight 3-State output buffers. The two sections of
each register are controlled independently by the clock (nCP) and
Output Enable (nOE
) control gates.
Each register is fully edge triggered. The state of each D input, one
set-up time before the LOW-to-HIGH clock transition, is transferred
to the corresponding flip-flop’s Q output.
The 3-State output buffers are designed to drive heavily loaded
3-State buses, MOS memories, or MOS microprocessors. Each
active-LOW Output Enable (nOE
) controls all eight 3-State buffers
for its register independent of the clock operation.
When nOE
is LOW, the stored data appears at the outputs for that
register. When nOE
is HIGH, the outputs for that register are in the
high-impedance “OFF” state, which means they will neither drive nor
load the bus.
FEATURES
• Two 8-bit positive edge triggered registers
• Live insertion/extraction permitted
• Power-up 3-State
• Power-up reset
• Multiple V
CC
and GND pins minimize switching noise
• 3-State output buffers
• Output capability: +64 mA/–32 mA
• 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
