TC74VHC374F/FW/FT
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74VHC374F,TC74VHC374FW,TC74VHC374FT
Octal D-Type Flip Flop with 3-State Output
The TC74VHC374 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.
An input protection circuit ensures that 0 to 5.5 V can be
applied to the input pins without regard to the supply voltage.
This device can be used to interface 5 V to 3 V systems and two
supply systems such as battery back up. This circuit prevents
device destruction due to mismatched supply and input voltages.
Features
High speed: fmax = 185 MHz (typ.) at VCC = 5 V
Low power dissipation: ICC = 4 µA (max) at Ta = 25°C
High noise immunity: VNIH = VNIL = 28% VCC (min)
Power down protection is provided on all inputs.
Balanced propagation delays: tpLH ∼− tpHL
Wide operating voltage range: VCC (opr) = 2 to 5.5 V
Low noise: VOLP = 0.9 V (max)
Pin and function compatible with 74ALS374
Note: xxxFW (JEDEC SOP) is not available in
Japan.

Note 1: Parameter guaranteed by design.
tosLH = |tpLHm tpLHn|, tosHL = |tpHLm tpHLn|
Note 2: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating
current consumption without load.
Average operating current can be obtained by the equation:
ICC (opr) = CPD·VCC·fIN + ICC/8 (per F/F)
And the total CPD when n pcs. of latch operate can be gained by the following equation:
CPD (total) = 20 + 12·n
