74VHC238
74VHC238 is 3 TO 8 LINE DECODER manufactured by STMicroelectronics.
3 TO 8 LINE DECODER s HIGH SPEED: t PD = 5.5 ns (TYP.) at VCC = 5V s LOW POWER DISSIPATION:
ICC = 4 µA (MAX.) at TA=25°C s HIGH NOISE IMMUNITY:
VNIH = VNIL = 28% VCC (MIN.)
)s POWER DOWN PROTECTION ON INPUTS t(ss SYMMETRICAL OUTPUT IMPEDANCE: c|IOH| = IOL = 8 m A (MIN) us BALANCED PROPAGATION DELAYS: dt PLH ≅ t PHL ros OPERATING VOLTAGE RANGE: PVCC(OPR) = 2V to 5.5V s PIN AND FUNCTION PATIBLE WITH te74 SERIES 238 les IMPROVED LATCH-UP IMMUNITY bso DESCRIPTION
The 74VHC238 is an advanced high-speed
- OCMOS 3 TO 8 LINE DECODER fabricated with )sub-micron silicon gate and double-layer metal t(swiring C2MOS technology.
If the device is enabled, 3 binary select inputs (A, c B, and C) determine which one of the outputs will ugo high. If enable input G1 is held low or either rod G2A or G2B is held high, decoding function is inhibited and all the 8 outputs go to low.
