TC7MA138FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7MA138FK
Low Voltage 3-to-8 Line Decoder with 3.6 V Tolerant Inputs and Outputs
The TC7MA138FK is a high performance CMOS 3-to-8 decoder.
Designed for use in 1.8, 2.5 or 3.3 V systems, it achieves high
speed operation while maintaining the CMOS low power
dissipation.
It is also designed with over voltage tolerant inputs and
outputs up to 3.6 V.
When the device is enabled, 3 binary select inputs (A, B and C)
determine which one of the outputs (Y0 - Y0) will go low.
When enable input G1 is held low or either G2A or G2B is held
high, decoding function is inhibited and all outputs go high.
G1, G2A and G2B inputs are provided to ease cascade
connection and for use as an address decoder for memory
systems.
All inputs are equipped with protection circuits against static
discharge.
Features
· Low voltage operation: VCC = 1.8~3.6 V
· High speed operation: tpd = 3.5 ns (max) (VCC = 3.0~3.6 V)
tpd = 4.1 ns (max) (VCC = 2.3~2.7 V)
tpd = 8.2 ns (max) (VCC = 1.8 V)
· 3.6 V tolerant inputs and outputs.
· Output current: IOH/IOL = ±24 mA (min) (VCC = 3.0 V)
IOH/IOL = ±18 mA (min) (VCC = 2.3 V)
IOH/IOL = ±6 mA (min) (VCC = 1.8 V)
· Latch-up performance: ±300 mA
· ESD performance: Machine model > ±200 V
Human body model > ±2000 V
· Package: VSSOP (US16)
· Power down protection is provided on all inputs and outputs.
Weight: 0.02 g (typ.)
