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.

74LCXH16245
Low Voltage 16-Bit Bidirectional Transceiver
with Bushold
General Description
Features
The LCXH16245 contains sixteen non-inverting bidirec-
tional buffers with 3-STATE outputs and is intended for bus
oriented applications. The device is designed for low volt-
age (2.5V or 3.3V) VCC applications with capability of inter-
■ 2.3V–3.6V VCC specifications provided
■ 4.5 ns tPD max (VCC 3.3V), 20 A ICC max
■ Power-down high impedance outputs
■ Bushold on inputs eliminates the need for external
pull-up/pull-down resistors
facing to a 5V signal environment. The device is byte
controlled. Each byte has separate control inputs which
could be shorted together for full 16-bit operation. The T/R
inputs determine the direction of data flow through the
device. The OE inputs disable both the A and B Ports by
placing them in a high impedance state.
■
24 mA output drive (VCC 3.0V)
■ Implements patented noise/EMI reduction circuitry
■ Latch-up performance conforms to the requirements of
JESD78
The LCXH16245 data inputs include active bushold cir-
cuitry, eliminating the need for external pull-up resistors to
hold unused or floating data inputs at a valid logic level.
■ ESD performance:
Human body model 2000V
Machine model 200V
The LCXH16245 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
■ Also packaged in plastic Fine-Pitch Ball Grid Array
(FBGA)
