SN74AVC16245 16-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS www.ti.com SCES142L – JULY 1998 – REVISED MAY 2005 • FEATURES • • • • • Member of the Texas Instruments Widebus™ Family EPIC™ (Enhanced-Performance Implanted CMOS) Submicron Process DOC™ (Dynamic Output Control) Circuit Dynamically Changes Output Impedance, Resulting in Noise Reduction Without Speed Degradation Less Than 2-ns Maximum Propagation Delay at 2.5-V and 3.3-V VCC Dynamic Drive Capability Is Equivalent to Standard Outputs With IOH and IOL of ±24 mA at 2.5-V VCC Overvoltage-Tolerant Inputs/Outputs Allow Mixed-Voltage-Mode Data Communications Ioff Supports Partial-Power-Down Mode Operation ESD Protection Exceeds JESD 22 – 2000-V Human-Body Model (A114-A) – 200-V Machine Model (A115-A) Latch-Up Performance Exceeds 250 mA Per JESD 78 Package Options Include Plastic Thin Shrink Small-Outline (DGG) and Thin Very Small-Outline (DGV) Packages • • • • DESCRIPTION A Dynamic Output Control (DOC™) circuit is implemented, which, during the transition, initially lowers the output impedance to effectively drive the load and, subsequently, raises the impedance to reduce noise. Figure 1 shows typical VOL vs IOL and VOH vs IOH curves to illustrate the output impedance and drive capability of the circuit. At the beginning of the signal transition, the DOC circuit provides a maximum dynamic drive that is equivalent to a high-drive standard-output device. For more information, refer to the TI application reports, AVC Logic Family Technology and Applications, literature number SCEA006, and Dynamic Output Control (DOC™) Circuitry Technology and Applications, literature number SCEA009. 3.2 TA = 25°C Process = Nominal - Output Voltage - V 2.8 2.4 VCC = 3.3 V 2.0 1.6 VCC = 2.5 V 1.2 OH VCC = 1.8 V 0.8 V VOL - Output Voltage - V 2.8 TA = 25°C Process = Nominal 2.4 2.0 1.6 1.2 0.8 VCC = 3.3 V 0.4 0.4 0 17 34 51 68 85 102 119 IOL - Output Current - mA 136 153 170 VCC = 2.5 V VCC = 1.8 V -160 -144 -128 -112 -96 -80 -64 -48 IOH - Output Current - mA -32 -16 0 Figure 1. Output Voltage vs Output Current This 16-bit (dual octal) noninverting bus transceiver is operational at 1.2-V to 3.6-V VCC, but is designed specifically for 1.65-V to 3.6-V VCC operation. The SN74AVC16245 is designed for asynchronous communication between data buses. The control-function implementation minimizes external timing requirements. This device can be used as two 8-bit transceivers or one 16-bit transceiver. It allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated. Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Products conform to specifications per the terms of the Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters. Copyright © 1998–2005, Texas Instruments Incorporated SN74AVC16245 16-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS www.ti.com SCES142L – JULY 1998 – REVISED MAY 2005 DESCRIPTION (CONTINUED) To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. The SN74AVC16245 is characterized for operation from –40°C to 85°C.
