4-to-16 line decoder/demultiplexer	74LV154

FEATURES

•Optimized for low voltage applications: 1.0 to 3.6 V

•Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V

•Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V, Tamb = 25°C

•Typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V,

Tamb = 25°C

•16-line demultiplexing capability

•Decodes 4 binary-coded inputs into one of 16 mutually exclusive outputs

•2-input enable gate for strobing or expansion

•Output capability: standard

•ICC category: MSI

DESCRIPTION

The 74LV154 is a low-voltage CMOS device and is pin and function compatible with 74HC/HCT154.

The 74LV154 decoders accept four active HIGH binary address inputs (A0 to A3) and provide 16 mutually exclusive active LOW

outputs(Y0 to Y15).

The 2-input enable inputs (E0, E1) can be used to strobe the decoder to eliminate the normal decoding ªglitchesº on the outputs, or it can be used for expansion of the decoder.

The enable input has two AND'ed inputs which must be LOW to enable the outputs.

The 74LV154 can be used as a 1-to-16 demultiplexer by using one of the enable inputs as the multiplexed data input.

When the other enable is LOW, the addressed output will follow the state of the applied data.

QUICK REFERENCE DATA

GND = 0 V; Tamb = 25°C; tr = tf ≤ 2.5 ns

	SYMBOL					PARAMETER	CONDITIONS	TYPICAL	UNIT
	tPHL/tPLH	Propagation delay					CL = 15 pF;		ns
		An, En to Yn					VCC = 3.3 V	11
	CI	Input capacitance						3.5	pF
	CPD	Power dissipation capacitance per gate					VI = GND to VCC1	60	pF

NOTE:

1.CPD is used to determine the dynamic power dissipation (PD in mW) PD = CPD × VCC2 × fi +S (CL × VCC2 × fo) where:

fi = input frequency in MHz; CL = output load capacitance in pF;

fo = output frequency in MHz; VCC = supply voltage in V;

S (CL × VCC2 × fo) = sum of the outputs.
