INTEGRATED CIRCUITS 74LVC16241A 16-bit buffer/line driver (3-State) Product specification Supersedes data of 1995 Dec 26 IC24 Data Handbook 1997 Jul 29 Philips Semiconductors Product specification 16-bit buffer/line driver (3-State) 74LVC16241A FEATURES PIN CONFIGURATION • 5 volt tolerant inputs/outputs for interfacing with 5V logic • Wide supply voltage range of 1.2V to 3.6V • Complies with JEDEC standard no. 8-1A • CMOS low power consumption • MULTIBYTETM flow-through standard pin-out architecture • Low inductance multiple power and ground pins for minimum noise and ground bounce • Direct interface with TTL levels DESCRIPTION The 74LVC16241A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. Inputs can be driven from either 3.3V or 5V devices. In 3-State operation, outputs can handle 5V. These features allow the use of these devices in a mixed 3.3V/5V environment. The 74LVC16241A is a 16-bit buffer/line driver with 3-State outputs. The 3-State outputs are controlled by the output enable inputs nOE and nOE. Schmitt-trigger action at all inputs makes the circuit highly tolerant for slower input rise and fall times. The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. 1OE 1 48 2OE 1Y0 2 47 1A0 1Y1 3 46 1A1 GND 4 45 GND 1Y2 5 44 1A2 1Y3 6 43 1A3 VCC 7 42 VCC 2Y0 8 41 2A0 2Y1 9 40 2A1 GND 10 39 GND 2Y2 11 38 2A2 2Y3 12 37 2A3 3Y0 13 36 3A0 3Y1 14 35 3A1 GND 15 34 GND 3Y2 16 33 3A2 3Y3 17 32 3A3 VCC 18 31 VCC 4Y0 19 30 4A0 4Y1 20 29 4A1 GND 21 28 GND 4Y2 22 27 4A2 4Y3 23 26 4A3 4OE 24 25 3OE SW00049 QUICK REFERENCE DATA GND = 0 V; Tamb = 25 C; tr = tf 2.5 ns PARAMETER SYMBOL tPHL/tPLH Propagation delay nAn to nYn CI Input capacitance CPD Power dissipation capacitance per buffer CONDITIONS TYPICAL UNIT 2.9 ns 5.0 pF 25 pF CL = 50pF VCC = 3.3V VI = GND to VCC1 NOTES: 1. CPD is used to determine the dynamic power dissipation (PD in W): PD = CPD x VCC2 x fi + (CL x VCC2 x fo) where: fi = input frequency in MHz; CL = output load capacity in pF; fo = output frequency in MHz; VCC = supply voltage in V; (CL x VCC2 x fo) = sum of outputs.
