74VCX16240 Low-Voltage 1.8/2.5/3.3V 16-Bit Buffer With 3.6 V–Tolerant Inputs and Outputs (3–State, Inverting) The 74VCX16240 is an advanced performance, inverting 16–bit buffer. It is designed for very high–speed, very low–power operation in 1.8 V, 2.5 V or 3.3 V systems. When operating at 2.5 V (or 1.8 V) the part is designed to tolerate voltages it may encounter on either inputs or outputs when interfacing to 3.3 V busses. It is guaranteed to be over–voltage tolerant to 3.6 V. The 74VCX16240 is nibble controlled with each nibble functioning identically, but independently. The control pins may be tied together to obtain full 16–bit operation. The 3–state outputs are controlled by an Output Enable (OEn) input for each nibble. When OEn is LOW, the outputs are on. When OEn is HIGH, the outputs are in the high impedance state. • Designed for Low Voltage Operation: VCC = 1.65–3.6 V • 3.6V Tolerant Inputs and Outputs • High Speed Operation: 2.5 ns max for 3.0 to 3.6 V • • • • • • 3.0 ns max for 2.3 to 2.7 V 6.0 ns max for 1.65 to 1.95 V Static Drive: ±24 mA Drive at 3.0 V ±18 mA Drive at 2.3 V ±6 mA Drive at 1.65 V Supports Live Insertion and Withdrawal IOFF Specification Guarantees High Impedance When VCC = 0 V Near Zero Static Supply Current in All Three Logic States (20 µA) Substantially Reduces System Power Requirements Latchup Performance Exceeds ±250 mA @ 125°C ESD Performance: Human Body Model >2000 V; Machine Model >200 V Semiconductor Components Industries, LLC, 2001 January, 2001 – Rev. 1 1 http://onsemi.com MARKING DIAGRAM 48 48 74VCX16240DT 1 AWLYYWW TSSOP–48 DT SUFFIX CASE 1201 A WL YY WW 1 = Assembly Location = Wafer Lot = Year = Work Week ORDERING INFORMATION Device Package Shipping 74VCX16240DT TSSOP 39 / Rail 74VCX16240DTR TSSOP 2500 / Reel Publication Order Number: 74VCX16240/D 74VCX16240 OE1 1 48 OE2 O0 2 47 D0 O1 3 46 D1 GND 4 1 OE1 OE3 48 OE2 OE4 25 24 45 GND O2 5 44 D2 O3 6 43 D3 VCC 7 42 VCC O4 8 41 D4 O5 9 40 D5 GND 10 D0:3 O0:3 D8:11 O8:11 D4:7 O4:7 D12:15 O12:15 One of Four 39 GND O6 11 38 D6 O7 12 37 D7 O8 13 36 D8 O9 14 35 D9 GND 15 34 GND O10 16 33 D10 O11 17 32 D11 VCC 18 31 VCC O12 19 30 D12 O13 20 29 D13 GND 21 28 GND O14 22 27 D14 O15 23 26 D15 OE4 24 25 OE3 Figure 2.
