TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
Octal Schmitt Bus Buffer
Inverted, 3-State Outputs
TC74VHCV244FK Non-Inverted, 3-State Outputs
The TC74VHCV240 and 244FK are advanced high speed CMOS OCTAL
BUS BUFFERs fabricated with silicon gate CMOS technology.
They achieve the high speed operation similar to equivalent Bipolar Schottky
TTL while maintaining the CMOS low power dissipation.
The 74VHCV240FK is an inverting 3-state buffer having two active-low
output enables. The TC74VHCV244FK is a non-inverting 3-state buffer, and
has two active-low output enables.
Input pin have hysteresis between the positive-going and negative-going
VSSOP20-P-0030-0.50 : 0.03 g ( typ.)
thresholds. Thus the TC74VHCV240 and 244FK are capable of squaring up
transitions of slowly changing input signals and provides an improved noise
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, etc.
Note: Output in off-state
High speed: tpd = 3.9 ns (typ.) at VCC = 5 V
Low power dissipation: ICC = 2 μA (max) at Ta = 25°C
Wide operating voltage range: VCC (opr) = 1.8 V to 5.5 V
Ouput current: |IOH|/IOL = 16 mA (min) (VCC = 4.5 V)
Available in VSSOP (US)
Power-down protection provided on all inputs and outputs
Pin and function compatible with the 74 series
(74AC/VHC/HC/F/ALS/LS etc.) 240/244 type
