The VHCT574A is an advanced high speed CMOS octal Note 1: Outputs in OFF-State. flip-flop with 3-STATE output fabricated with silicon gate CMOS technology. It achieves the high speed operation Features similar to equivalent Bipolar Schottky TTL while maintain- ing the CMOS low power dissipation. This 8-bit D-type flip- � High speed: f = 140 MHz (typ) at T = 25°C MAX A flop is controlled by a clock input (CP) and an Output � Power Down Protection is provided on all inputs and Enable input (OE). When the OE input is HIGH, the eight outputs. outputs are in a high impedance state. � Low Noise: V = 1.6V (max) OLP Protection circuits ensure that 0V to 7V can be applied to the input and output (Note 1) pins without regard to the � Low Power Dissipation: supply voltage. This device can be used to interface 3V to I = 4 μA (max) @ T = 25°C CC A 5V systems and two supply systems such as battery back � Pin and Function Compatible with 74HCT574 Ordering Code: Order Number Package Number Package Description 74VHCT574AM M20B 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300 Wide 74VHCT574ASJ M20D 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74VHCT574AMTC MTC20 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 74VHCT574AN N20A 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Surface mount packages are also available on Tape and Reel.
