Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers

will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor

product management systems do not have the ability to manage part nomenclature that utilizes an underscore

(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain

device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated

device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

email any questions regarding the system integration to Fairchild_questions@onsemi.com.

74VCX162373

Low Voltage 16-Bit Transparent Latch

with 3.6V Tolerant Inputs and Outputs

and 26: Series Resistors in Outputs

General Description

The VCX162373 contains sixteen non-inverting latches

with 3-STATE outputs and is intended for bus oriented

Features

■ 1.4V–3.6V V_CCsupply operation

■ 3.6V tolerant inputs and outputs

applications. The device is byte controlled. The flip-flops

appear to be transparent to the data when the Latch enable

(LE) is HIGH. When LE is LOW, the data that meets the

setup time is latched. Data appears on the bus when the

Output Enable (OE) is LOW. When OE is HIGH, the out-

puts are in a high impedance state.

■ 26 series resistors in outputs

■ t_PD(I_nto O_n)

3.3 ns max for 3.0V to 3.6V V_CC

The VCX162373 is also designed with 26 resistors in the

outputs. This design reduces line noise in applications

such as memory address drivers, clock drivers and bus

transceivers/transmitters.

■ Power-off high impedance inputs and outputs

■ Support live insertion and withdrawal (Note 1)

■ Static Drive (I_OH/I_OL

)

12 mA @ 3.0V V_CC

The 74VCX162373 is designed for low voltage (1.4V to

3.6V) V_CCapplications with I/O compatibility up to 3.6V.

■ Uses proprietary noise/EMI reduction circuitry

■ Latch-up performance exceeds 300 mA

■ ESD performance:

The 74VCX162373 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing low CMOS power dissipation.

Human body model 2000V

Machine model 200V

Note 1: To ensure the high-impedance state during power up or power

down, OE should be tied to V

through a pull-up resistor; the minimum

CC

value of the resistor is determined by the current-sourcing capability of the

driver.

Functional Description

The 74VCX162373 contains sixteen edge D-type latches

with 3-STATE outputs. The device is byte controlled with

each byte functioning identically, but independent of the

other. Control pins can be shorted together to obtain full

16-bit operation. The following description applies to each

byte. When the Latch Enable (LE_n) input is HIGH, data on

its I input changes. When LE_nis LOW, the latches store

information that was present on the I inputs a setup time

preceding the HIGH-to-LOW transition on LE_n. The

3-STATE outputs are controlled by the Output Enable

(OE_n) input. When OE_nis LOW the standard outputs are in

the 2-state mode. When OE_nis HIGH, the standard outputs

the I_nenters the latches. In this condition the latches are

transparent, i.e., a latch output will change state each time

are in the high impedance mode but this does not interfere

with entering new data into the latches.
