I
IH
High-level input current
The current into* an input when a high-level voltage is applied to that input
I
IL
Low-level input current
The current into* an input when a low-level voltage is applied to that input
I
off
Input/output power-off leakage current
The maximum leakage current into* an input or output terminal of the device with the specified voltage
applied to the terminal and V
CC
= 0 V
I
OH
High-level output current
The current into* an output with input conditions applied that, according to the product specification,
establishes a high level at the output
I
OHS
Static high-level output current
The static and testable current into* a DOC circuit output with input conditions applied that, according
to the product specifications, establishes a static high level at the output. The dynamic drive current is
not specified for devices with DOC circuit outputs because of its transient nature; however, it is similar
to the dynamic drive current that is available from a high-drive (nondamping resistor) standard-output
device.
I
OL
Low-level output current
The current into* an output with input conditions applied that, according to the product specification,
establishes a low level at the output
I
OLS
Static low-level output current
The static and testable current into* a DOC circuit output with input conditions applied that, according
to the product specifications, establishes a static low level at the output. The dynamic drive current is
not specified for devices with DOC circuit outputs because of its transient nature; however, it is similar
to the dynamic drive current that is available from a high-drive (nondamping resistor) standard-output
device.
I
OZ
Off-state (high-impedance state) output current (of a 3-state output)
The current flowing into* an output with the input conditions applied that, according to the product
specification, establishes the high-impedance state at the output
I
OZPD
Power-down off-state (high-impedance state) output current (of a 3-state output)
The current flowing into* an output that is switched to or held in the high-impedance state as the device
is being powered down to V
CC
= 0 V
I
OZPU
Power-up off-state (high-impedance state) output current (of a 3-state output)
The current flowing into* an output that is switched to or held in the high-impedance state as the device
is being powered up from V
CC
= 0 V
jitter Jitter
Dispersion of a time parameter of the pulse waveforms in a pulse train with respect to a reference time,
interval, or duration. Unless otherwise specified by a mathematical adjective, peak-to-peak jitter is
assumed.
jitter(RMS) RMS jitter
The root mean square jitter, one-sixth of the maximum peak-to-peak jitter
*Current out of a terminal is given as a negative value.
