INTEGRATED CIRCUITS 74ALVCH162244 16-bit buffer/line driver with 30Ω termination resistor (3-State) Product specification IC24 Data Handbook 1998 Jun 29 Philips Semiconductors Product specification 16-bit buffer/line driver with 30 termination resistor (3-State) FEATURES 74ALVCH162244 PIN CONFIGURATION • 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 VCC and ground pins for minimum noise and ground bounce • Direct interface with TTL levels • Bus hold on all data inputs • Integrated 30Ω termination resistor DESCRIPTION The 74ALVCH162244 is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. The 74ALVCH162244 is a 16-bit non-inverting buffer/line driver with 3-State outputs. The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. The 3-State outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on nOE causes the outputs to assume a high impedance OFF-state. The 74ALVCH162244 is designed with 30Ω series resistors in both HIGH and LOW output states. The 74ALVCH162244 has active bus hold circuitry which is provided to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors. 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 SW00194 QUICK REFERENCE DATA GND = 0 V; Tamb = 25°C; tr = tf ≤ 2.5 ns PARAMETER SYMBOL tPHL/tPLH Propagation delay An to Yn CI Input capacitance CPD Power dissipation capacitance per buffer CONDITIONS TYPICAL UNIT 3.0 2.7 ns 5.0 pF VCC = 2.5V, CL = 30pF VCC = 3.3V, CL = 50pF VI = GND to VCC1 Outputs enabled 25 Outputs disabled 4 pF NOTES: 1.
