TC74VCX16543FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX16543FT Low-Voltage 16-Bit Registered Transceiver with 3.6-V Tolerant Inputs and Outputs The TC74VCX16543FT is a high performance CMOS 16-bit registered transceiver. Designed for use in 1.8-V, 2.5-V or 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. It is also designed with overvoltage tolerant inputs and outputs up to 3.6 V. The TC74VCX16543FT can be used as two 8-bit transceivers or one 16-bit transceiver. Separate latch-enable (LEAB or LEBA) and output-enable (OEAB or OEBA) inputs are provided for each register to permit independent control in either direction of data Weight: 0.25 g (typ.) flow. The A-to-B enable (CEAB) input must be low in order to enter data from A or to output data from B. If CEAB is low and LEAB is low, the A-to-B latches are transparent; a subsequent low-to-high transition of LEAB puts the A latches in the storage mode. With CEAB and OEAB both low, the 3-state B outputs are active and reflect the data present at the output of the A latches. Data flow from B to A is similar but requires using the CEBA, LEBA, and OEAB inputs. When the OE input is high, the outputs are in a high-impedance state. This device is designed to be used with 3-state memory address drivers, etc. All inputs are equipped with protection circuits against static discharge. Features (Note) • Low-voltage operation: VCC = 1.8 to 3.6 V • High-speed operation: tpd = 3.5 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 4.0 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 8.0 ns (max) (VCC = 1.8 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 = 1.8 V) • Latch-up performance: −300 mA • ESD performance: Machine model ≥ ±200 V Human body model ≥ ±2000 V • Package: TSSOP • Bidirectional interface between 2.5 V and 3.3 V signals. • 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 TC74VCX16543FT Pin Assignment (top view) IEC Logic Symbol 1OEAB 1 56 1OEBA 1LEAB 2 55 1LEBA 1CEAB 3 54 1CEBA GND 4 53 GND 1A1 5 52 1OEBA 1CEBA 1LEBA 1OEAB 1CEAB 1LEAB 2OEBA 1B1 1A2 6 51 1B2 VCC 7 50 VCC 2CEBA 2LEBA 2OEAB 2CEAB 2LEAB 1A3 8 49 1B3 1A4 9 48 1B4 1A5 10 47 1B5 GND 11 46 GND 1A2 1A6 12 45 1B6 1A3 1A7 13 44 1B7 1A4 1A8 14 43 1B8 1A5 2A1 15 42 2B1 1A6 2A2 16 41 2B2 1A7 2A3 17 40 2B3 1A8 GND 18 39 GND 2A1 2A4 19 38 2B4 2A5 20 37 2B5 2A2 2A6 21 36 2B6 2A3 VCC 22 35 VCC 2A4 2A7 23 34 2B7 2A8 24 33 2B8 GND 25 32 GND 2CEAB 26 31 2CEBA 2LEAB 27 30 2LEBA 2OEAB 28 29 2OEBA 1A1 56 54 55 1 3 2 29 31 30 28 26 27 5 1EN3 G1 C5 2EN4 G2 2C6 7EN9 G7 7C11 8EN10 G8 8C12 3 6D 52 1B1 4 6 51 1B2 8 49 1B3 9 48 10 47 12 45 13 44 14 43 15 9 12D 11D 42 1B4 1B5 1B6 1B7 1B8 2B1 10 16 41 17 40 19 38 2A5 20 37 2B5 2A6 21 36 2B6 23 34 24 33 2A7 2A8 2 5D 2B2 2B3 2B4 2B7 2B8 2007-10-19 TC74VCX16543FT Truth Table (A bus → B bus each 8-bit latch) Inputs CEAB LEAB OEAB A Outputs B H X X X Z X X H X Z L H L X L L L L L L L L H H Note: B0 (Note) Output level before the indicated steady-state input conditions were established.
