INTEGRATED CIRCUITS 74ALVCH16821 20-bit bus-interface D-type flip-flop; positive-edge trigger (3-State) Product specification IC24 Data Handbook 1998 May 29 Philips Semiconductors Philips Semiconductors Product specification 20-bit bus-interface D-type flip-flop; positive-edge trigger (3-State) 74ALVCH16821 FEATURES * Wide supply voltage range of 1.2V to 3.6V * Complies with JEDEC standard no. 8-1A * Current drive 24 mA at 3.0 V * CMOS low power consumption * Direct interface with TTL levels * MULTIBYTETM flow-through standard pin-out architecture * Low inductance multiple VCC and ground pins for minimum noise and ground bounce 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 D input, one set-up time before the Low-to-High clock transition, is transferred to the corresponding flip-flop's Q 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. * All data inputs have bus hold * Output drive capability 50 transmission lines @ 85C QUICK REFERENCE DATA SYMBOL tPHL/tPLH CI CPD Fmax GND = 0V; Tamb = 25C; tr = tf 2.5ns PARAMETER Propagation delay nCP to nQn Input capacitance Power dissipation capacitance per buffer Maximum clock frequency CONDITIONS VCC = 2.5V, CL = 30pF VCC = 3.3V, CL = 50pF Outputs enabled Outputs disabled TYPICAL 2.6 2.5 5.0 33 17 250 350 UNIT ns pF pF MHz VI = GND to VCC1 VCC = 2.5V, CL = 30pF VCC = 3.3V, CL = 50pF NOTE: 1. CPD is used to determine the dynamic power dissipation (PD in mW): PD = CPD x VCC2 x fi + S (CL x VCC2 x fo) where: fi = input frequency in MHz; CL = output load capacitance in pF; fo = output frequency in MHz; VCC = supply voltage in V; S (CL x VCC2 x fo) = sum of outputs.
