• High efficiency (η = 90% or higher) (@VIN = 5V, VOUT = 3.3V, and IOUT = 300 mA).
• Operating voltage (VIN) range: 3 to 5.5 V
• Low on-resistance (RDS(ON)): 0.27 Ω (typ.) if VIN = 5 V
• Low on-resistance (RDS(ON)): 0.27 Ω (typ.) if VIN = 5 V
• High oscillation frequency of 550 kHz (typ.), making it possible to use small external components.
• Uses external phase compensation, assuring a high degree of design freedom in selecting external components and determining a loop response.
• Employs a current mode architecture with excellent fast load response.
• A small surface mount-type ceramic capacitor can be used as an output smoothing capacitor.
• Housed in a small surface-mount package (PS-8) with a low thermal resistance.

Desciption
The TD74BC574P/TD74BC574F is a high-speed 8-bit flip-flop fabricated with silicon gate Bi-CMOS technology. It achieves the high-speed operation equivalent to the FAST family while
maintaining the Bi-CMOS low-power dissipation. The TD74BC574P/F is a non-inverting flip-flop. Each bit is individually controlled by a clock input (CK) and an output enable input (OE). When the OE input is high, all eight outputs are in the high-impedance state, which facilitates the interface with bus lines. All inputs are equipped with resistors and diodes to protect
against Electrostatic Discharge (ESD).

Features
• High-speed operation ........................ tpd = 8.8 ns (typ.)
• Symmetrical output impedance ....... IOH = −3 mA (max) IOL = 24 A (max)
• Low power dissipation ...................... ICCD = 7 mA (typ.) ICCZ = 10 ?A (typ.)
• Operating temperature range .......... Ta = −40°C to 85°C
• High ESD protection ......................... 2000 V (MIL standard)
• Pin and function compatible with FAST (74F574)
