Octal D-Type Flip-Flop with 3-State Output
The TC74VHCT574A is an advanced high speed CMOS OCTAL
FLIP-FLOP with 3-STATE OUTPUT fabricated with silicon gate
C2MOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
This 8-bit D-type flip-flop is controlled by a clock input (CK)
and a output enable input ( OE ).
When the OE input is high, the eight outputs are in a high
impedance state.
The input voltage are compatible with TTL output voltage.
This device may be used as a level converter for interfacing 3.3
V to 5 V system.
Input protection and output circuit ensure that 0 to 5.5 V can
be applied to the input and output (Note) pins without regard to
the supply voltage. These structure prevents device destruction
due to mismatched supply and input/output voltages such as
battery back up, hot board insertion, etc.
Note: Output in off-state
Features
High speed: fmax = 140 MHz (typ.) at VCC = 5 V
Low power dissipation: ICC = 4 µA (max) at Ta = 25°C
Compatible with TTL outputs: VIL = 0.8 V (max)
VIH = 2.0 V (min)
Power down protection is provided on all inputs and outputs.
Balanced propagation delays: tpLH ∼− tpHL
Low noise: VOLP = 1.6 V (max)
Pin and function compatible with the 74 series
(74AC/HC/F/ALS/LS etc.) 574 type.
Note: xxxFW (JEDEC SOP) is not available in
Japan.
