- 2000-V Human-Body Model (A114-A)
- 200-V Machine Model (A115-A)
- 1000-V Charged-Device Model (C101)
This 18-bit universal bus driver is designed for 2.3-V
to 3.6-V VCC operation.
Data
flow
from
A
to
Y
is
controlled
by
the
output-enable (OE) input. The device operates in the
transparent mode when the latch-enable (LE) input is
high. When LE is low, the A data is latched if the
clock (CLK) input is held at a high or low logic level. If
LE is low, the A data is stored in the latch/flip-flop on
the low-to-high transition of CLK. When OE is high,
the outputs are in the high-impedance state.
The
SN74ALVCF162835
has
series
damping
resistors in the device output structure that reduce
switching noise in 128-MB and 256-MB SDRAM
modules. Designed with a drive capability of
±18 mA,
this
device
is
a
midway
drive
between
the
SN74ALVC162835 (
±12 mA) and SN74ALVC16835
(
±24 mA).
