Low-Voltage CMOS 16-Bit
Transparent Latch
With 5V-Tolerant Inputs and Outputs
(3-State, Non-Inverting)
transparent latch operating from a 2.7 to 3.6V supply. The device is byte
controlled. Each byte has separate Output Enable and Latch Enable
inputs. These control pins can be tied together for full 16–bit operation.
High impedance TTL compatible inputs significantly reduce current
loading to input drivers while TTL compatible outputs offer improved
switching noise performance. A V I specification of 5.5V allows
MC74LCX16373 inputs to be safely driven from 5V devices.
5V–tolerant outputs. When the Latch Enable (LEn) inputs are 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 outputs are controlled by the Output Enable
(OEn) inputs. When OE is LOW, the 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.
