1 / 6 page © 2002 Fairchild Semiconductor Corporation DS500628 www.fairchildsemi.com September 2001 Revised February 2002 74ALVCH162374 Low Voltage 16-Bit D-Type Flip-Flop with Bushold and 26 Ω Series Resistors in Outputs General Description The ALVCH162374 contains sixteen non-inverting D-type flip-flops with 3-STATE outputs and is intended for bus ori- ented applications. The device is byte controlled. A buff- ered clock (CP) and output enable (OE) are common to each byte and can be shorted together for full 16-bit opera- tion. The ALVCH162374 data inputs include active bushold cir- cuitry, eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level. The 74ALVCH162374 is also designed with 26 Ω series resistors in the outputs. This design reduces line noise in applications such as memory address drivers, clock drivers and bus transceivers/transmitters. The 74ALVCH162374 is designed for low voltage (1.65V to 3.6V) VCC applications with output compatibility up to 3.6V. The 74ALVCH162374 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation. Features s 1.65V to 3.6V VCC supply operation s 3.6V tolerant control inputs and outputs s Bushold data inputs eliminates the need for external pull-up/pull-down resistors s 26 Ω series resistors in outputs s tPD (CLK to On) 4.6 ns max for 3.0V to 3.6V VCC 5.4 ns max for 2.3V to 2.7V VCC 9.6 ns max for 1.65V to 1.95V VCC s Uses patented noise/EMI reduction circuitry s Latch-up conforms to JEDEC JED78 s ESD performance: Human body model > 2000V Machine model > 200V Ordering Code: Devices also available in Tape and Reel.
