     1998 Feb 13 Philips Semiconductors Product specification 2.5V/3.3V 16-bit bus transceiver/register (3-State) FEATURES 74ALVT16652 DESCRIPTION • 16–bit bus interface • 5V I/O Compatible • 3-State buffers • Output capability: +64mA/-32mA • TTL input and output switching levels • Input and output interface capability to systems at 5V supply • Bus-hold data inputs eliminate the need for external pull-up The 74ALVT16652 is a high-performance BiCMOS product designed for VCC operation at 2.5V or 3.3V with I/O compatibility up to 5V. The device can be used as two 8-bit transceivers or one 16-bit transceiver. Complimentary output-enable (OEAB and OEBA) inputs are provided to control the transceiver functions. Select-control (SAB and SBA) inputs are provided to select whether real-time or stored data is transferred. A Low-input level selects real-time data, and a High input level selects stored data. The circuitry used for select control eliminates the typical decoding glitch that occurs in a multiplexer during the transition between stored and real-time data. resistors to hold unused inputs • Live insertion/extraction permitted • Power-up reset • Power-up 3-State • No bus current loading when output is tied to 5V bus • Latch-up protection exceeds 500mA per JEDEC JC40.2 Std 17 • ESD protection exceeds 2000V per MIL STD 883 Method 3015 Data on the A or B bus, or both, can be stored in the internal flip-flops by Low-to-High transitions at the appropriate clock (CPAB or CPBA) inputs regardless of the levels on the select-control or output-enable inputs. When SAB and SBA are in real-time transfer mode, it is possible to store data without using the internal D-type flip-flops by simultaneously enabling OEAB and OEBA. In this configuration, each output reinforces its input. Thus, when all other data sources to the two sets of bus lines are at high impedance, each set of bus lines remains at its last level configuration. and 200V per Machine Model QUICK REFERENCE DATA SYMBOL TYPICAL CONDITIONS Tamb = 25°C PARAMETER tPLH tPHL Propagation delay nAx to nBx or nBx to nAx CL = 50pF UNIT 2.5V 3.3V 2.0 2.1 1.5 1.6 ns pF CIN Input capacitance DIR, OE VI = 0V or VCC 3 3 CI/O I/O pin capacitance VI/O = 0V or VCC 9 9 pF ICCZ Total supply current Outputs disabled 40 70 µA ORDERING INFORMATION TEMPERATURE RANGE OUTSIDE NORTH AMERICA NORTH AMERICA DWG NUMBER 56-Pin Plastic SSOP Type III PACKAGES –40°C to +85°C 74ALVT16652 DL AV16652 DL SOT371-1 56-Pin Plastic TSSOP Type II –40°C to +85°C 74ALVT16652 DGG AV16652 DGG SOT364-1 LOGIC SYMBOL (IEEE/IEC) 56 1 55 54 2 3 5 EN1(BA) EN2(AB) C3 G4 C5 G6

Data input functions are always enabled, i.e., data at the bus pins will be stored on every Low-to-High transition of the clock. If both Select controls (nSAB and nSBA) are Low, then clocks can occur simultaneously. If either Select control is High, the clocks must be staggered in order to load both registers. 1998 Feb 13 4 Philips Semiconductors Product specification 2.5V/3.3V 16-bit bus transceiver/register (3-State) The following examples demonstrate the four fundamental bus-management functions that can be performed with the 74ALVT16652.
