TC74VCX164245FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX164245FT 16-Bit Dual Supply Bus Transceiver The TC74VCX164245FT is a dual supply, advanced high-speed CMOS 16-bit dual supply voltage interface bus transceiver fabricated with silicon gate CMOS technology. It is also designed with over voltage tolerant inputs and outputs up to 3.6 V. Designed for use as an interface between a 3.3-V or 2.5-V bus and a 2.5-V or 1.8-V bus in mixed 3.3-V or 2.5-V/2.5-V or 1.8-V supply systems. The B-port interfaces with the 3.3-V or 2.5-V bus, the A-port with the 2.5-V or 1.8-V bus. Weight: 0.25 g (typ.) The direction of data transmission is determined by the level of the DIR input. The enable input ( OE ) can be used to disable the device so that the buses are effectively isolated. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features (Note) • Bidirectional interface between 3.3 V and 2.5 V, 3.3 V and 1.8 V, 2.5 V and 1.8 V • High-speed: tpd = 4.6 ns (max) (VCCB = 3.3 ± 0.3 V, VCCA = 2.5 ± 0.2 V) • tpd = 7.1 ns (max) (VCCB = 3.3 ± 0.3 V, VCCA = 1.8 ± 0.15 V) • tpd = 7.0 ns (max) (VCCB = 2.5 ± 0.2 V, VCCA = 1.8 ± 0.15 V) • Output current: IOH/IOL = ±24 mA (min) (VCC = 3.0 V) : IOH/IOL = ±18 mA (min) (VCC = 2.3 V) : IOH/IOL = ±6 mA (min) (VCC = 1.65 V) • Latch-up performance: −300 mA • ESD performance: Machine model ≥ ±200 V Human body model ≥ ±2000 V • Package: TSSOP • 3.6-V tolerant function and power-down protection provided on all inputs and outputs Note: Do not apply a signal to any bus pins when it is in the output mode. Damage may result. All floating (high impedance) bus pins must have their input level fixed by means of pull-up or pull-down resistors. 1 2007-10-19 TC74VCX164245FT Pin Assignment (top view) IEC Logic Symbol 1DIR 1 48 1OE 1B1 2 47 1A1 1B2 3 46 1A2 GND 4 45 GND 1B3 5 44 1A3 1B4 6 43 1A4 VCCB 7 42 VCCA 1B5 8 41 1A5 1B6 9 40 1A6 GND 10 39 GND 1B7 11 38 1A7 1B8 12 37 1A8 2B1 13 36 2A1 2B2 14 35 2A2 GND 15 34 GND 2B3 16 33 2A3 2B4 17 32 2A4 VCCB 18 31 VCCA 2B5 19 30 2A5 2B6 20 29 2A6 GND 21 28 GND 2B7 22 27 2A7 2B8 23 26 2A8 2DIR 24 25 2OE 1OE 1DIR 2OE 2DIR 1A1 1A2 1A3 1A4 1A5 1A6 1A7 1A8 2A1 2A2 2A3 2A4 2A5 2A6 2A7 2A8 2 48 1 25 24 47 46 44 43 41 40 38 37 36 35 33 32 30 29 27 26 G3 3 EN1 (BA) 3 EN2 (AB) G6 6 EN4 (BA) 6 EN5 (AB) 2 1 2 4 5 1B1 3 5 6 8 9 11 12 13 1B2 1B3 1B4 1B5 1B6 1B7 1B8 2B1 14 16 17 19 20 22 23 2B2 2B3 2B4 2B5 2B6 2B7 2B8 2007-10-19 TC74VCX164245FT Truth Table Inputs Function 1OE 1DIR Bus 1A1-1A8 Bus 1B1-1B8 Outputs L L Output Input A=B L H Input Output B=A H X Z Inputs Z Function 2OE 2DIR Bus 2A1-2A8 Bus 2B1-2B8 Outputs L L Output Input A=B L H Input Output B=A H X Z Z X: Don’t care Z: High impedance 3 2007-10-19 TC74VCX164245FT Block Diagram VCCB 1DIR VCCA Logic level converter 1OE 1B1 1B8 1A1 Same as above block VCCB 2DIR 2OE VCCA Logic level converter 2B1 2B8 1A8 2A1 Same as above block 4 2A8 2007-10-19 TC74VCX164245FT Absolute Maximum Ratings (Note 1) Characteristics Power supply voltage (Note 2) DC input voltage (DIR, OE ) Symbol Rating Unit VCCB −0.5 to 4.6 VCCA −0.5 to VCCB VIN −0.5 to 4.6 V V −0.5 to 4.6 (Note 3) VI/OB −0.5 to VCCB + 0.5 (Note 4) DC bus I/O voltage V −0.5 to 4.6 (Note 3) VI/OA −0.5 to VCCA + 0.5 (Note 4) IIK −50 II/OK ±50 IOUTB ±50 IOUTA ±50 ICCB ±100 ICCA ±100 Power dissipation PD 400 mW Storage temperature Tstg −65 to 150 °C Input diode current Output diode current DC output current DC VCC/ground current per supply pin mA (Note 5) mA mA mA Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
