74LVT16646A
3.3 V 16-bit bus transceiver; 3-state
Rev. 03 -- 12 January 2005 Product data sheet
1. General description
The 74LVT16646A is a high-performance BiCMOS product designed for VCC operation at 3.3 V. This device is a 16-bit transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The control function implementation minimizes external timing requirements. The device features an output enable (OE) input for easy cascading and a direction (DIR) input for direction control. Data on bus A or bus B is clocked into the registers on the LOW-to-HIGH transition of the appropriate clock (CPAB or CPBA). The select control (SAB and SBA) inputs can multiplex stored and real-time (transparent mode data).

All typical values are measured at VCC = 3.3 V and Tamb = 25 C. For valid test results, data must not be loaded into the flip-flops (or latches) after applying power. Unused pins at VCC or GND. This is the bus hold overdrive current required to force the input to the opposite logic state. This parameter is valid for VCC = 0 V to 1.2 V with a transition time of up to 10 ms. From VCC = 1.2 V to 3.3 V 0.3 V. A transition time of 100 s is permitted. This parameter is valid for Tamb = 25 C only. ICC is measured with outputs pulled to VCC or GND. This is the increase in supply current for each input at the specified voltage level other than VCC or GND.

Please consult the most recently issued data sheet before initiating or completing a design. The product status of the device(s) described in this data sheet may have changed since this data sheet was published. The latest information is available on the Internet at URL http://www.semiconductors.philips.com. For data sheets describing multiple type numbers, the highest-level product status determines the data sheet status.
16. Definitions
Short-form specification -- The data in a short-form specification is extracted from a full data sheet with the same type number and title. For detailed information see the relevant data sheet or data handbook. Limiting values definition -- Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 60134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information -- Applications that are described herein for any of these products are for illustrative purposes only. Philips Semiconductors make no representation or warranty that such applications will be suitable for the specified use without further testing or modification.
17. Disclaimers
