74ALVCH16821 20-bit bus-interface D-type flip-flop; positive-edge trigger; 3-state Rev. 3 — 2 February 2018 1 Product data sheet General description The 74ALVCH16821 has two 10-bit, edge triggered registers, with each register coupled to a 3-state output buffer. The two sections of each register are controlled independently by the clock (nCP) and output enable (nOE) control gates. Each register is fully edge triggered. The state of each nDn input, one set-up time before the Low-to-High clock transition, is transferred to the corresponding flip-flop’s nQn output. When nOE is LOW, the data in the register appears at the outputs. When nOE is HIGH, the outputs are in high impedance OFF state. Operation of the nOE input does not affect the state of the flip-flops. The 74ALVCH16821 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 from 1.2 V to 3.6 V CMOS low-power consumption Direct interface with TTL levels Current drive ± 24 mA at 3.0 V MULTIBYTE flow-through standard pin-out architecture Low inductance multiple VCC and GND pins for minimum noise and ground bounce Output drive capability 50 Ω transmission lines at 85°C All data inputs have bushold Complies with JEDEC standard no. 8-1A 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 74ALVCH16821DGG Package Temperature range Name Description −40 °C to +85 °C plastic thin shrink small outline package; 56 leads; SOT364-1 body width 6.1 mm TSSOP56 Version 74ALVCH16821 Nexperia 20-bit bus-interface D-type flip-flop; positive-edge trigger; 3-state 4 Functional diagram 1OE 1CP 1 56 28 2OE 29 2CP 55 54 52 51 49 48 47 45 44 1D0 1D1 1D2 1D3 1D4 1D5 1D6 1D7 1D8 1D9 2D0 2D1 2D2 2D3 2D4 2D5 2D6 2D7 2D8 2D9 43 1D0 1D1 1D2 1D3 1D4 1D5 1D6 1D7 1D8 1D9 56 1CP 1 1OE 1Q0 1Q1 1Q2 1Q3 1Q4 1Q5 1Q6 1Q7 1Q8 1Q9 2 3 5 6 8 9 10 12 13 14 42 41 40 38 37 36 34 33 31 30 2D0 2D1 2D2 2D3 2D4 2D5 2D6 2D7 2D8 2D9 29 2CP 28 2OE 2Q0 2Q1 2Q2 2Q3 2Q4 2Q5 2Q6 2Q7 2Q8 2Q9 15 16 17 19 20 21 23 24 26 27 55 54 52 51 49 48 47 45 44 43 42 41 40 38 37 36 34 33 31 30 EN2 C1 EN4 C3 1D 2 3D 4 2 3 5 6 8 9 10 12 13 14 15 16 17 19 20 21 23 24 26 27 001aad155 001aad153 Figure 1. Logic symbol nD0 1Q0 1Q1 1Q2 1Q3 1Q4 1Q5 1Q6 1Q7 1Q8 1Q9 2Q0 2Q1 2Q2 2Q3 2Q4 2Q5 2Q6 2Q7 2Q8 2Q9 Figure 2. IEC logic symbol nD1 nD2 nD3 nD4 nD5 nD6 nD7 nD8 nD9 D D D D D D D D D D CP Q CP Q CP Q CP Q CP Q CP Q CP Q CP Q CP Q CP Q nCP nOE nQ0 nQ1 nQ2 nQ3 nQ4 nQ5 nQ6 nQ7 nQ8 nQ9 001aad156 Figure 3. Logic diagram 74ALVCH16821 Product data sheet All information provided in this document is subject to legal disclaimers.
