OCTAL TRANSPARENT D-TYPE LATCH WITH 3-STATE OUTPUTS

Description

Pin Assignments

The 74LVC373A provides eight transparent D-type latches. While the

latch-enable (LE) input is high, the Q outputs follow the data (D)

inputs. When LE is taken low, the Q outputs are latched at the logic

levels set up at the D inputs. A buffered output-enable (OE) input can

be used to place the eight outputs in either a normal logic state (high

or low logic levels) or the high-impedance state. In the high-impedance

state, the outputs neither load nor drive the bus lines significantly. The

high-impedance state and increased drive provide the capability to

drive bus lines without interface or pullup components. OE does not

affect the internal operations of the latches. Old data can be retained

or new data can be entered while the outputs are in the high-

impedance state.

The device is designed for operation with a power supply range of

1.65V to 3.6V.

The inputs are tolerant to 5.5V allowing this device to be used in a

mixed voltage environment. The device is fully specified for partial

Applications

•

General Purpose Logic

power down applications using I_OFF

. The I_OFFcircuitry disables the

Bus Driving

output preventing damaging current backflow when the device is

powered down.

All devices are:

Totally Lead-Free & Fully RoHS compliant (Notes 1 & 2)

Halogen and Antimony Free. “Green” Device (Note 3)

Notes:

1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.

2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen and Antimony free,

"Green" and Lead-Free.

3. Halogen and Antimony free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and

<1000ppm antimony compounds.
