ON MC74LCX573DW Low-voltage cmos octal transparent latch flow through pinout with 5 v−tolerant inputs and outputs (3−state, non−inverting) Datasheet

MC74LCX573
Low−Voltage CMOS
Octal Transparent Latch
Flow Through Pinout
With 5 V−Tolerant Inputs and Outputs
(3−State, Non−Inverting)
The MC74LCX573 is a high performance, non−inverting octal
transparent latch operating from a 2.3 to 3.6 V supply. High
impedance TTL compatible inputs significantly reduce current
loading to input drivers while TTL compatible outputs offer improved
switching noise performance. A VI specification of 5.5 V allows
MC74LCX573 inputs to be safely driven from 5.0 V devices.
The MC74LCX573 contains 8 D−type latches with 3−state standard
outputs. When the Latch Enable (LE) input is HIGH, data on the Dn
inputs enters the latches. In this condition, the latches are transparent,
i.e., a latch output will change state each time its D input changes.
When LE is LOW, the latches store the information that was present
on the D inputs a setup time preceding the HIGH−to−LOW transition
of LE. The 3−state standard outputs are controlled by the Output
Enable (OE) input. When OE is LOW, the standard outputs are
enabled. When OE is HIGH, the standard outputs are in the high
impedance state, but this does not interfere with new data entering into
the latches. The LCX573 flow through design facilitates easy PC
board layout.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
