inputs/outputs; 3-state

Product data sheet
1. General description
The 74LVC16373A-Q100 and 74LVCH16373A-Q100 are 16-bit D-type transparent
latches featuring separate D-type inputs with bus hold (74LVCH16373A-Q100 only) for
each latch and 3-state outputs for bus-oriented applications. One Latch Enable (LE) input
and one Output Enable (OE) are provided for each octal. Inputs can be driven from either
3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied to the outputs. These
features allow the use of these devices in mixed 3.3 V and 5 V applications.
The device consists of two sections of eight D-type transparent latches with 3-state true
outputs. When LE is HIGH, data at the Dn inputs enter the latches. In this condition, the
latches are transparent, that is, the latch outputs change each time its corresponding
D-input changes. The latches store the information that was present at the D-inputs one
set-up time (t
su
) preceding the HIGH-to-LOW transition of LE. When OE is LOW, the
contents of the eight latches are available at the outputs. When OE is HIGH, the outputs
go to the high impedance OFF-state. Operation of the OE input does not affect the state of
the latches. Bus hold on the data inputs eliminates the need for external pull-up resistors
to hold unused inputs.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
