74ALVCH16827 20-bit buffer/line driver, non-inverting 3-state Rev. 3 6 April 2018 Product data sheet 1 General description The 74ALVCH16827 is a 20-bit non-inverting buffer/driver with 3-state outputs for bus oriented applications. The 74ALVCH16827 consists of two 10-bit sections with separate output enable signals. For either 10-bit buffer section, the two output enable (1OE0 and 1OE1 or 2OE0 and 2OE1) inputs must both be active. If either output enable input is high, the outputs of that 10-bit buffer section are in high impedance state. The 74ALVCH16827 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. 2 Features and benefits Wide supply voltage range of 1.2V to 3.6V CMOS low power consumption MultiByte flow-through standard pin-out architecture Low inductance multiple V and GND pins for minimum noise and ground bounce CC Direct interface with TTL levels (2.7 V to 3.6 V) Bus hold on data inputs Output drive capability 50 transmission lines at 85 C Current drive 24 mA at 3.0 V Complies with JEDEC standards: JESD8-5 (2.3 V to 2.7 V) JESD8B/JESD36 (2.7 V to 3.6 V) ESD protection: HBM ANSI/ESDA/JEDEC JS-001 exceeds 2000 V CDM JESD22-C101E exceeds 1000 V 3 Ordering information Table 1.Ordering information Type number Package Temperature Name Description Version range 74ALVCH16827DGG 40 C to +85 C TSSOP56 plastic thin shrink small outline package 56 leads SOT364-1 body width 6.1 mmNexperia 74ALVCH16827 20-bit buffer/line driver, non-inverting 3-state 4 Functional diagram 1 & EN1 56 28 & EN2 29 55 2 1 1 54 3 55 54 52 51 49 48 47 45 44 43 52 5 51 6 1A0 1A1 1A2 1A3 1A4 1A5 1A6 1A7 1A8 1A9 49 8 1 1OE0 48 9 47 10 56 1OE1 45 12 1Y0 1Y1 1Y2 1Y3 1Y4 1Y5 1Y6 1Y7 1Y8 1Y9 44 13 43 14 2 3 5 6 8 9 10 12 13 14 42 15 1 2 41 16 42 41 40 38 37 36 34 33 31 30 40 17 38 19 2A0 2A1 2A2 2A3 2A4 2A5 2A6 2A7 2A8 2A9 37 20 28 2OE0 36 21 34 23 29 2OE1 33 24 2Y0 2Y1 2Y2 2Y3 2Y4 2Y5 2Y6 2Y7 2Y8 2Y9 31 26 30 27 15 16 17 19 20 21 23 24 26 27 001aad056 001aad055 Figure 1.Logic symbol Figure 2.IEC logic symbol nA0 nA1 nA2 nA3 nA4 nA5 nA6 nA7 nA8 nA9 nOE0 nOE1 nY0 nY1 nY2 nY3 nY4 nY5 nY6 nY7 nY8 nY9 001aad061 Figure 3.Logic diagram V CC data input to internal circuit 001aal733 Figure 4.Bus hold circuit 74ALVCH16827 All information provided in this document is subject to legal disclaimers.
