3-to-8 Line Decoder
The MC74VHC138 is an advanced high speed CMOS 3to8 decoder
fabricated with silicon gate CMOS technology. It achieves high speed
operation similar to equivalent Bipolar Schottky TTL while maintaining
CMOS low power dissipation.
When the device is enabled, three Binary Select inputs (A0 A2)
determine which one of the outputs (Y0 Y7) will go Low. When enable input
E3 is held Low or either E2 or E1 is held High, decoding function is inhibited
and all outputs go high. E3, E2, and E1 inputs are provided to ease cascade
connection and for use as an address decoder for memory systems.
The internal circuit is composed of three stages, including a buffer output
which provides high noise immunity and stable output. The inputs tolerate
voltages up to 7V, allowing the interface of 5V systems to 3V systems.
High Speed: tPD = 5.7ns (Typ) at VCC = 5V
Low Power Dissipation: ICC = 4
A (Max) at TA = 25
C
High Noise Immunity: VNIH = VNIL = 28% VCC
Power Down Protection Provided on Inputs
Balanced Propagation Delays
Designed for 2V to 5.5V Operating Range
Low Noise: VOLP = 0.8 V (Max)
Pin and Function Compatible with Other Standard Logic Families
Latchup Performance Exceeds 300mA
ESD Performance: HBM > 2000V; Machine Model > 200V
Chip Complexity: 122 FETs or 30.5 Equivalent Gates

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this highimpedance cir-
cuit. For proper operation, Vin and
Vout should be constrained to the
range GND
v
(Vin or Vout)
v
VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
