74AVCH16244
74AVCH16244 is 16-bit buffer/line driver manufactured by Nexperia.
description The 74AVCH16244 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 n OE. A HIGH on n OE causes the outputs to assume a high impedance OFF-state. The 74AVCH16244 is designed to have an extremely fast propagation delay and a minimum amount of power consumption. To ensure the high-impedance output state during power-up or power-down, n OE should be tied to VCC through a pull-up resistor (Live Insertion). A dynamic controlled output (DCO) circuitry is implemented to support termination line drive during transient (see Figure 4). The 74AVCH16244 has active bus-hold circuitry 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. 2 Features and benefits - Wide supply voltage range from 1.2 V to 3.6 V - CMOS low power consumption - Low inductance multiple VCC and GND pins for minimum noise and ground bounce - Input/output tolerant up to 3.6 V - Dynamic controlled output (DCO) circuit dynamically changes the output impedance, resulting in noise reduction without speed degradation - Bus hold on all data inputs - Supports Live Insertion - plies with JEDEC standards: - JESD8-7 (1.2 V to 1.95 V) - JESD8-5 (1.8 V to 2.7 V) - JESD8-1A (2.7 V to 3.6 V) 3 Ordering information Table 1. Ordering information Type number Package Temperature range 74AVCH16244DGG - 40 °C to +85 °C Name TSSOP48 Description plastic thin shrink small outline package; 48 leads; body width 6.1 mm Version SOT362-1 Nexperia 4 Functional diagram 47 1A0 46 1A1 44 1A2 43 1A3 1 1OE 2 36 1Y0 3A0 3 35 1Y1 3A1 5 33 1Y2 3A2 6 32 1Y3 3A3 25 3OE 41...
