Revised August 2003 74VCXH16244 Low Voltage 16-Bit Buffer/Line Driver with Bushold General Description The VCXH16244 contains sixteen non-inverting buffers with 3-STATE outputs to be employed as a memory and address driver, clock driver, or bus oriented transmitter/ receiver. The device is nibble (4-bit) controlled. Each nibble has separate 3-STATE control inputs which can be shorted together for full 16-bit operation. The VCXH16244 data inputs include active bushold circuitry, eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level. The 74VCXH16244 is designed for low voltage (1.2V to 3.6V) VCC applications with output capability up to 3.6V. The 74VCXH16244 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation. Features ■ 1.2V to 3.6V VCC supply operation ■ 3.6V tolerant control inputs and outputs ■ Bushold on data inputs eliminating the need for external pull-up/pull-down resistors ■ tPD 2.5 ns max for 3.0V to 3.6V VCC ■ Static Drive (IOH/IOL) ±24 mA @ 3.0V VCC ■ Uses patented noise/EMI reduction circuitry ■ Latch-up performance exceeds 300 mA ■ ESD performance: Human body model > 2000V Machine model > 200V ■ Also packaged in plastic Fine-Pitch Ball Grid Array (FBGA) (Preliminary) Ordering Code: Order Number 74VCXH16244G (Note 1)(Note 2) Package Number BGA54A (Preliminary) 74VCXH16244MTD (Note 2) MTD48 Package Description 54-Ball Fine-Pitch Ball Grid Array (FBGA), JEDEC MO-205, 5.5mm Wide 48-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 6.1mm Wide Note 1: Ordering Code “G” indicates Tray.

When OEn is LOW, the outputs are in the 2-state mode. When OEn is HIGH, the standard outputs are in the high impedance mode but this does not interfere with entering new data into the inputs. The 74VCXH16244 contains sixteen non-inverting buffers with 3-STATE outputs. The device is nibble (4 bits) controlled with each nibble functioning identically, but independent of each other. The control pins may be shorted together to obtain full 16-bit operation.The 3-STATE out- Logic Diagram 3 www.fairchildsemi.com 74VCXH16244 Functional Description 74VCXH16244 Absolute Maximum Ratings(Note 3) Recommended Operating Conditions (Note 5) Supply Voltage (VCC) −0.5V to +4.6V DC Input Voltage (VI) −0.5V to +4.6V Power Supply −0.5V to +4.6V Input Voltage Output Voltage (VO) Operating Outputs 3-STATED Outputs Active (Note 4) −0.5V to VCC +0.5V DC Input Diode Current (IIK) VI < 0V Output Voltage (VO) −50 mA DC Output Diode Current (IOK) VO < 0V −50 mA VO > VCC +50 mA ±50 mA 0.0V to VCC 0.0V to 3.6V VCC = 3.0V to 3.6V ±24 mA VCC = 2.3V to 2.7V ±18 mA VCC = 1.65V to 2.3V ±6 mA VCC = 1.4V to 1.6V DC VCC or GND Current per ±100 mA Supply Pin (I CC or GND) Storage Temperature Range (TSTG) Output in Active States Output in 3-STATE Output Current in IOH/IOL DC Output Source/Sink Current (IOH/IOL) 1.2V to 3.6V −0.3V to +3.6V ±2 mA VCC = 1.2V −65°C to +150°C ±100 µA Free Air Operating Temperature (TA) −40°C to +85°C Minimum Input Edge Rate (∆t/∆V) VIN = 0.8V to 2.0V, VCC = 3.0V 10 ns/V Note 3: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed.
