     1998 Aug 04 Philips Semiconductors Product specification 18-bit bus interface D-type latch (3-State) FEATURES 74ALVCH16843 PIN CONFIGURATION • Wide supply voltage range of 1.2V to 3.6V • Complies with JEDEC standard no. 8-1A. • CMOS low power consumption • Direct interface with TTL levels • Current drive ± 24 mA at 3.0 V • MULTIBYTETM flow-through standard pin-out architecture • Low inductance multiple VCC and GND pins for minimum noise and ground bounce • All data inputs have bus hold • Output drive capability 50Ω transmission lines @ 85°C DESCRIPTION The 74ALVCH16843 has two 9–bit D-type latch featuring separate D-type inputs for each latch and 3-State outputs for bus oriented applications. The two sections of each register are controlled independently by the latch enable (nLE), clear (nCLR), preset (nPRE) and output enable (nOE) control gates. When nOE is LOW, the data in the registers appear at the outputs. When nOE is HIGH, the outputs are in the high impedance OFF state. Operation of the nOE input does not affect the state of the flip-flops. The 74ALVCH16843 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. 1CLR 1 56 1OE 2 55 1Q0 3 54 1D0 GND 4 53 GND 1Q1 5 52 1D1 1Q2 6 51 1D2 VCC 7 50 VCC 1Q3 8 49 1D3 1Q4 9 48 1D4 1Q5 10 47 1D5 GND 11 46 GND 1Q6 12 45 1D6 1Q7 13 44 1D7 1Q8 14 43 1D8 2Q0 15 42 2D0 2Q1 16 41 2D1 2Q2 17 40 2D2 GND 18 39 GND 2Q3 19 38 2D3 2Q4 20 37 2D4 1LE 1PRE 2Q5 21 36 2D5 VCC 22 35 VCC 2Q6 23 34 2D6 2Q7 24 33 2D7 GND 25 32 GND 2Q8 26 31 2D8 2OE 27 30 2PRE 2CLR 28 29 2LE SH00143 QUICK REFERENCE DATA GND = 0V; Tamb = 25°C; tr = tf ≤ 2.5ns PARAMETER SYMBOL Propagation delay nDn to nQn tPHL/tPLH Propagation delay nLE to nQn CI Input capacitance CPD Power dissipation dissi ation capacitance ca acitance per er buffer CONDITIONS VCC = 2.5V, CL = 30pF VCC = 3.3V, CL = 50pF VCC = 2.5V, CL = 30pF VCC = 3.3V, CL = 50pF VI = GND to VCC1 TYPICAL 2.2 2.1 2.3 2.0 5.0 transparent mode Output enabled Output disabled 17 3 Clocked mode Output enabled Output disabled 19 9 UNIT ns ns pF pF F NOTES: 1.
