LT TIL308, TIL309 NUMERIC DISPLAYS WITH LOGIC SLBS002-D1096, MARCH 1972-REVISED SEPTEMBER 1992 description These internally-driven seven-segment light-emitting-diode (LED) displays contain a five-bit latch and a decoder/LED driver in a single 16-pin package. A description of the functions of the inputs and outputs of these devices are in the terminal function table. The TTL MSI circuits contain the equivalent of 78 gates on a single chip. Logic inputs and outputs are completely TTL/DTL compatible. The buffered inputs are implemented with relatively large resistors in series with the bases of the input transistors to lower drive-current requirements to one-half of that required for a standard Series 54/74 TTL input. Some of the additional features of these displays are as follows: * * * * * * * * * Latched BCD and decimal point logic outputs provided to drive logic processors simultaneously with the displayed data Minimum number of inputs required . . . 4-line BCD plus decimal point Overriding blanking for suppressing entire display or pulse-modulation of LED brightness LED test input to simultaneously turn on all display segments and decimal point Can be operated in a real-time mode or latched-update-only mode by use of the latch strobe input Displays numbers 0 through 9 as well as A, C, E, F, or minus sign Can be blanked by entry of BCD 13 or by use of the blanking input Decimal point controlled independently with decimal-point latch Constant-current-source TTL-LED interface for optimum performance. The latch outputs except QDP are active pullup, and each one, except QDP, is capable of driving three standard Series 54/74 loads. The LED driver outputs are designed specifically to maintain a relatively constant on-level current of approximately 7 mA through each LED segment and decimal point. All inputs are diode-clamped to minimize transmission-line effects, thereby simplifying system design. Power dissipation is typically 575 mW with all segments on. Terminal Functions PIN NAME BLANKING Input (BI) Latch Data Inputs A, B, C, D, DP Latch Outputs QA, QB, QC, QD, QDP LATCH STROBE Input (LS) LED TEST Input (LT) NO. 11 15, 10, 6, 7, 12 4, 1, 2, 3, 14 5 13 DESCRIPTION When low, will blank (turn off) the entire display. Mus be high for normal operation of the display. Data on these inputs are entered into the latches under the control of the latch strobe input. The binary weights of the inputs are: A = 1, B = 2, C = 4, D = 8. DP is decimal point latch data input. The BCD data that drives the decoder is stored in the five latches and is available at these outputs. The binary weights of the outputs are: QA = 1, QB = 2, QC = 4, QD = 8. QDP is decimal point latch output. When low, the data in latches follow the data on the latch inputs. When high, the data in the latches are held constant and are unaffected by new data on the latch inputs. When low, will turn on the entire display, overriding the data in the latches and the blanking input. Must be high for normal operation of the display.
