INTEGRATED CIRCUITS 74ALVT16652 2.5V/3.3V 16-bit bus transceiver/register (3-State) Product specification Supersedes data of 1996 Aug 13 IC23 Data Handbook 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 1 1 4 3D 4 1 6 1 1 6 2 5D 52 29 28 30 31 27 26 EN7(BA) EN8(AB) C9 G10 C11 G12 15 1 7 10 1 11D 12 1 1 12 6 51 16 8 49 17 9 48 19 10 47 20 12 45 21 13 44 23 14 43 24 10 9D 42 8 41 40 38 37 36 34 33 SW00158 1998 Feb 13 2 853-1854 18962 Philips Semiconductors Product specification 2.5V/3.3V 16-bit bus transceiver/register (3-State) PIN CONFIGURATION 74ALVT16652 LOGIC SYMBOL 1OEAB 1 56 1OEBA 1CPAB 2 55 1CPBA 1SAB 3 54 1SBA GND 4 53 GND 1A0 5 52 1B0 1A1 6 51 1B1 VCC 7 50 VCC 2 1CPAB 1A2 8 49 1B2 3 1SAB 1OEAB 1 1A3 9 48 1B3 54 1SBA 1OEBA 56 1A4 10 47 1B4 55 1CPBA GND 11 46 GND 1A5 12 45 1B5 1A6 13 44 1B6 1A7 14 43 1B7 2A0 15 42 2B0 5 6 8 9 10 12 13 14 1A0 1A1 1A2 1A3 1A4 1A5 1A6 1A7 1AB 1B1 1B2 1B3 1B4 1B5 1B6 1B7 52 51 49 48 47 45 44 43 15 16 17 19 20 21 23 24 2A1 16 41 2B1 2A2 17 40 2B2 2A0 2A1 2A2 2A3 2A4 2A5 2A6 2A7 GND 18 39 GND 27 2CPAB 2A3 19 38 2B3 26 2SAB 2OEAB 28 2A4 20 37 2B4 31 2SBA 2OEBA 29 30 2CPBA 2A5 21 36 2B5 VCC 22 35 VCC 2A6 23 34 2B6 2A7 24 33 2B7 2AB 2B1 2B2 2B3 2B4 2B5 2B6 2B7 42 GND 25 32 GND 2SAB 26 31 2SBA 2CPAB 27 30 2CPBA 20EAB 28 29 2OEBA 41 40 38 37 36 34 33 SH00046 SW00159 PIN DESCRIPTION PIN NUMBER SYMBOL 2, 55, 27, 30 1CPAB, 1CPBA, 2CPAB, 2CPBA Clock input A to B / Clock input B to A 3, 54, 26, 31 1SAB, 1SBA, 2SAB, 2SBA Select input A to B / Select input B to A 5, 6, 8, 9, 10, 12, 13, 14 15, 16, 17, 19, 20, 21, 23, 24 1A0 – 1A7, 2A0 – 2A7 Data inputs/outputs (A side) 52, 51, 49, 48, 47, 45, 44, 43 42, 41, 40, 38, 37, 36, 34, 33 1B0 – 1B7, 2B0 – 2B7 Data inputs/outputs (B side) 1, 56, 28, 29 1OEAB, 1OEBA, 2OEAB, 2OEBA 4, 11, 18, 25, 32, 39, 46, 53 GND Ground (0V) 7, 22, 35, 50 VCC Positive supply voltage 1998 Feb 13 NAME AND FUNCTION Output enable inputs 3 Philips Semiconductors Product specification 2.5V/3.3V 16-bit bus transceiver/register (3-State) 74ALVT16652 LOGIC DIAGRAM nOEBA nOEAB nCPBA nSBA nCPAB nSAB 1of 8 Channels 1D C1 Q nA0 nB0 1D C1 Q nA1 nB1 nA2 nB2 nA3 nB3 nA4 nB4 DETAIL A X 7 nA5 nB5 nA6 nB6 nA7 nB7 SH00065 FUNCTION TABLE INPUTS H L X ↑ * ** DATA I/O OPERATING MODE nOEAB nOEBA nCPAB nCPBA nSAB nSBA nAx nBx L L H H H or L ↑ H or L ↑ X X X X Input Input Isolation Store A and B data X H H H ↑ ↑ H or L ↑ X ** X X Input Unspecified output* Store A, Hold B Store A in both registers L L X L H or L ↑ ↑ ↑ X X X ** Unspecified output* Input Hold A, Store B Store B in both registers L L L L X X X H or L X X L H Output Input Real time B data to A bus Stored B data to A bus H H H H X H or L X X L H X X Input Output Real time A data to B bus Store A data to B bus H L H or L H or L H H Output Output Stored A data to B bus Stored B data to A bus = = = = High voltage level Low voltage level Don’t care Low-to-High clock transition The data output function may be enabled or disabled by various signals at the nOEBA and nOEAB inputs.

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.
