The TC74VHCV240 and 244 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 74VHCV240 is an inverting 3-state buffer having two
active-low output enables. The TC74VHCV244 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 thresholds. Thus the TC74VHCV240 and 244 are
capable of squaring up transitions of slowly changing input
signals and provides an improved noise immunity.
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
Features
• 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 TSSOP and 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
